17. The Big Bang Theory (2007)
The Big Bang Theoryis one of those shows you either love or hate. Whichever side you’re on, it’s hard to deny the overwhelming popularity of the show. I enjoyed it right down to the end.
Just don’t go into it taking all of the nerd culture too seriously, otherwise some of the show’s (often unflattering) portrayal of geeks will rub you the wrong way. It’s shallow, but it’s fun.

16. Two and a Half Men (2003)
Two and a Half Menis one of those shows that deserves respect purely for the fact that it managed to keep going successfully after losing one of its main characters.
Charlie Sheen’s struggles with drug addiction and rehab are well-documented, and he was ultimately written out of the show during the eighth season.
Most shows would’ve called it quits, but instead of canceling,Two and a Half Menbrought in Ashton Kutcher and kept right on going. Was the show as good? Maybe not, but it was still good enough to enjoy!

15. Malcolm in the Middle (2000)
Arriving right at the turn of the millennium,Malcolm in the Middlenow stands tall to an entire generation of people as one of the most memorable and hilarious sitcoms of the 2000s.
The tales of the Wilkerson family took the country (and the world) by storm, with young fans everywhere recognizing some part of their own family within the dynamic displayed on screen.
The cast was arguably the show’s greatest strength, with the series particularly famous for making the career of Bryan Cranston (who memorably portrayed the father of the family, Hal).
In the end,Malcolm in the Middleremains a show that lives fondly in the hearts of not only its original audience, but modern ones, too.

14. Arrested Development (2003)
Of all the shows that redefined what a sitcom could be,Arrested Developmenttook the most outlandish path. The producers and creators seemed to throw away all that had come before, all to blaze their own trails in ways unseen up to that point.
Of course, looking back at it now,Arrested Developmentwas clearly ahead of its time. Despite three perfect seasons—complete with a multi-layered writing style that became instantly iconic—the show was just too smart for its own good for audiences of its time.
While its eventual return with seasons four and five were a letdown, those initial three seasons went on to inspire all kinds of richly complex sitcoms that succeeded on the foundations set byArrested Development.

13. Peep Show (2003)
Peep Show, the cult classic UK show that’s best summed-up as the inner thoughts of two self-deprecating men, would go on to find an even bigger audience in the years after it left the air.
Fronted by David Mitchell and Robert Webb, the iconic UK comedians quickly took hold of their roles and pushed them to places even further than the first season could’ve ever imagined.
During its run,Peep Showhad a dedicated fanbase but it was far from universally popular—the kind of show that only grows in awareness over time. In retrospect,Peep Showonly gets better with every episode, especially during seasons two through six.
Although the quality did drop after that, it still made for amazing TV. And fortunately for us, the show’s creator Jesse Armstrong would eventually go on to createSuccession!

12. The Inbetweeners (2008)
For a TV series that wasn’t really embraced much outside of the UK,The Inbetweenersbecame far greater than the sum of its parts. This endlessly quotable show depicts the lives of four British high school students and their place in school society.
The mark of any great series is to always leave fans wanting more. In the case ofThe Inbetweeners, fans so desperately wanted more that it eventually spawned a follow-up movie.
Few shows ever get the chance to cap off with a movie, and those that do tend to drop the ball.The Inbetweenersbucked that trend with a movie that was so successful, they got another one!
Long story short, you may not know aboutThe Inbetweenersif you aren’t in the UK, but the show is a UK jewel that became a cultural sensation and is remembered as one of the best sitcoms of the 2000s.

11. The Office (2001)
Here we have one of the most influential sitcoms since the turn of the millennium, the one that popularized the mockumentary format and started a trend that’s still going hot today.
The UK version ofThe Officehas now been copied and replicated by countless countries around the world, all of which have taken the premise and put their own local spin on it, infusing it with their own cultural mores, dynamics, and influences.
But it’s easy to forget just how funny Ricky Gervais and Stephen Merchant’s original series really was. Despite only running for two seasons and two specials, its impact touched the whole world.

10. How I Met Your Mother (2005)
Let’s get one point out of the way:How I Met Your Motherhad a terrible ending. However, everything leading up to that ending is fantastic, heartfelt, funny, and rewatchable.
The overarching plot of a father telling his children a painfully long story helped it stand out in the crowded sitcom genre, but it was the cast and characters that made it so warmly inviting to watch every week. Every major character on the show brought something to the table.
How I Met Your Motherran for nine seasons with 208 episodes—that’s one massive story those kids sat through!

9. Community (2009)
Dan Harmon’s quirky sitcomCommunitywill finally get its much-demanded movie in the near future. It’s one that will round out the show’s overall narrative, much to the delight of fans.
But even without that movie, the show’s six seasons are enough on their own to cementCommunity’s status as one of the greatest sitcoms ever.
Communitytook a lot of risks—more successes than failures—and its metanarrative was revolutionary for television of the time. Equipped with an incredible cast of comedic greats,Communitypushed the limits of what a sitcom could be.
In fact, much ofCommunity’s charm eventually ended up in Dan Harmon’s animated seriesRick and Morty. ButCommunityitself is a masterpiece that we’ll always remember fondly.

8. The Thick of It (2005)
Easily one of the most influential comedy series ever made, it’s a shame that so many people haven’t seenThe Thick of It, created by Armando Iannucci and written by Jesse Armstrong (the aforementioned creator of bothPeep ShowandSuccession).
In delving into one small department in the UK government,The Thick of Itproves so engrossing because it depicts a hard truth: real government issues are basically handled in the same, chaotic ways.
Featuring out-of-touch people who are trying to stay in power and keep in step with public interest,The Thick of Itfinds its humor in its stellar writing and performances. Even so, among the greats, it’s Peter Capaldi’s Malcolm Tucker that shines as the most iconic.

7. Curb Your Enthusiasm (2000)
If you thinkSeinfeldwas the greatest sitcom of the 90s, then you’ll absolutely loveCurb Your Enthusiasm. Given that it’s written by Larry David—one of the creators ofSeinfeld—the parallels make sense.
But in the case of this HBO sitcom, Larry David isn’t just a writer for the show. He’s the star! And he puts in fantastic performances, season after season, as the oblivious old man who just doesn’t get society.
Curb Your Enthusiasmis one of the greatest sitcoms of all time, and the fact that it’s been running for over two decades (and still going!) should be enough evidence that there’s something special here.

6. Parks and Recreation (2009)
Parks and Recreationis a hilarious show with an incredibly simple premise, as many of the best sitcoms tend to be. We get a glimpse into the folly and incompetence of the Parks and Recreation Department in the fictional town of Pawnee, Indiana.
This satirical mockumentary series—created by the minds that gave us other comedic hits likeThe Office,The Good Place, andBrooklyn Nine-Nine—features some of the funniest actors and actresses in the sitcom game, and each one brings their own flavor to the show.
Of course, it’s really Nick Offerman who carries the show as Ron Swanson, but all of the main characters are entertaining in their own way.

5. It’s Always Sunny in Philadelphia (2005)
If there was ever a show that’s starkly you-love-it-or-hate-it, it’d have to beIt’s Always Sunny in Philadelphia. This sitcom about the world’s most toxic friend group is a lot likeSeinfeldif everyone was absurdly despicable.
But there’s a lot of humor to be mined in watching these terrible people do terrible things, all while lacking the self-awareness to see that they’re the reasons why their lives are so miserable.
It’s Always Sunny in Philadelphiademands suspension of disbelief, but if you’re able to do that, it’s downright hilarious. It’s the ultimate anti-sitcom, and its subversion of tropes is always a breath of fresh air.
4. The King of Queens (1998)
AlthoughThe King of Queenstechnically came out in the late 90s, the bulk of its run took place in the 2000s. So, we’re counting it!
The show is centered around a fat guy (played by Kevin James) and his out-of-his-league wife (played by Leah Remini) as they go through their daily lives and deal with all the troubles that come their way.
Like all the best sitcoms, there’s a wrinkle in the form of a father-in-law (played by the late Jerry Stiller) who lives in the basement. It’s the comfortable dynamic between these three—and their friends—that makes for a funny show that’s easy to watch and enjoy.
3. Modern Family (2009)
Some may disagree withModern Family’s inclusion on this list solely because it debuted in 2009. That’s admittedly pretty late in the decade, but it certainly feels like a show from the 2000s!
Unlike most sitcoms of the time,Modern Familyemploys an ensemble cast to depict three different families who are all related yet exist across a broad spectrum of cultures, identities, and norms.
Most notably,Modern Familywas one of the first major sitcoms to feature a gay couple as main characters. (Prior to this, the most iconic gay characters on TV were Will and Jack onWill & Grace.)
From its handling of delicate relationships to its accurate depictions of growing up in so many different ways,Modern Familyjust does a lot right. And to top it off, it’s hilarious!
2. The Office (2005)
We’ve already featured the UK version ofThe Officeearlier on this list, but it’s really the US version ofThe Officethat blew up and popularized two big sitcom trends: mockumentary satire and cringe humor.
To this day, the Dunder Mifflin crew is one of the most iconic casts of characters in television history, andThe Officeremains one of the most-watched (and most-rewatched) sitcoms of our time.
Every episode brings something new to the table. And like all great sitcoms, it’s not always about humor as the show manages to tug on your heartstrings quite a bit throughout its long, successful run.
It’s hard to think of a 2000s-era sitcom that’s more enduring and more beloved worldwide, which earnsThe Officethis spot on the list.

1. Scrubs (2001)
Scrubsisn’t just my favorite sitcom of the 2000s, but it’s also my favorite TV show of all time. When I started working on this list, this was the only show that had a locked position from minute one.
Without exaggeration,Scrubsis a masterpiece of modern television. Creator Bill Lawrence—who later went on to co-createTed Lasso—knows how to blend comedy, drama, and pathos to perfection.
One minute you’re laughing, and the next you’re crying, and then you’re back to laughing again. You’re always feeling something when you watchScrubs, and those emotions are always earned.
Ask any doctor what the most realistic medical TV show is. Most of them will point to this one.Scrubsis grounded, practical, heartfelt, goofy, serious, warm, chilling, and oh-so addictive. Without a doubt, it’s our pick for the greatest sitcom of the 2000s.
