‘It’s Always Sunny in Philadelphia’ Season 18 Release Date, Time & Preview
The wait is over for fans of Paddy’s Pub. It’s Always Sunny in Philadelphia Season 18 begins airing tonight, Monday, August 17, at 9 p.m. on FXX, FX, and Hulu, with international streaming available on Disney+.
The timing feels almost poetic, since the premiere date lands exactly on the calendar day fans have circled for weeks. The Gang returns for an expanded ten-episode season, a jump from the eight episodes that made up each of the previous three seasons.
‘It’s Always Sunny in Philadelphia’ Season 18 Release Date and Premiere Details
Season 18 marks a real change in pace for the show, arriving roughly one year after Season 17 wrapped, unlike the two year gaps fans had grown used to between recent seasons. In fact, this is the first time since Season 14 back in 2019 that a new season has landed just one year after the last one.
‘It’s Always Sunny in Philadelphia’ remains the longest running live action sitcom in television history, a title it now holds by a wide margin. The show made that record official when it surpassed ‘The Adventures of Ozzie and Harriet’ in total seasons back in December 2021, and it has kept extending that lead ever since.
The renewal for this season actually goes all the way back to December 10, 2020, when the show was renewed through an eighteenth season. Charlie Day later revealed on The Today Show that the Season 18 writers room would begin work in October 2025, with filming for the new episodes starting up in February 2026.
‘It’s Always Sunny in Philadelphia’ Season 18 Cast and Returning Favorites
The core Gang remains intact, with Charlie Day, Glenn Howerton, series creator Rob Mac, Kaitlin Olson, and Danny DeVito all back to run the failing dive bar Paddy’s Pub into the ground once again. That kind of consistency after eighteen seasons is rare in television, and it is a big part of why the show has managed to hold its cult following for two decades.
Behind the scenes footage that surfaced from Rob Mac’s docuseries ‘Welcome to Wrexham’ gave fans an early look at production, including glimpses of episodes referred to in the footage as ‘2026: A Virtual Insanity,’ ‘The Gang Gets Tested,’ and ‘The Gang Goes to the Ren Faire.’
That same footage reportedly confirmed the return of a recurring character named Luther McDonald, which lines up with details that leaked from a script fans had already been buzzing about online.
One dangling thread from the Season 17 finale involves Frank proposing marriage to Sam, played by Carol Kane, and it remains unclear whether Kane will be back to see that storyline through. Given how beloved her chemistry with Danny DeVito’s Frank became last season, her potential return is one of the more talked about mysteries heading into the premiere.
‘It’s Always Sunny in Philadelphia’ Season 18 Plot and What to Expect
According to the official synopsis, the Gang gets tangled up in an inheritance dispute, wrestles with workplace automation, dives headfirst into conspiracy theories, and even tries to repair its image by sponsoring a Little League baseball team. It is exactly the kind of chaotic, of the moment premise the show has built its reputation on for nearly twenty years.
FX has teased that the new season leans into inheritances, automation anxiety, conspiracy theories, and society’s shifting relationship with sobriety, all while keeping the chaos at Paddy’s Pub cranked up to a new level. FX has also promised some of the series’ most outrageous moments yet, along with a heavy dose of star cameos and references to both Philadelphia culture and classic television comedy.
Fans can still catch up on the previous seventeen seasons on Hulu and Disney+, though five controversial episodes have been permanently removed from circulation due to their use of blackface. That context has followed the show for years now, and it is worth keeping in mind as new viewers dive into the back catalog ahead of tonight’s premiere.
‘It’s Always Sunny in Philadelphia’ Season 18 Trailer and Production Team
The first trailer arrived ahead of the premiere with the tagline “the only thing generated is more chaos,” a nod to a fake AI generated poster the series had dropped earlier in the promotional rollout. It is a very on brand piece of marketing for a show that has spent eighteen seasons mocking whatever cultural moment happens to be trending.
Behind the camera, the season is executive produced by series creator Rob Mac alongside Day, Howerton, Michael Rotenberg, Nicholas Frenkel, David Hornsby, Rob Rosell, Scott Marder, Dave Chernin, John Chernin, and Vanessa McGee, with FX Productions producing the series. That deep bench of longtime collaborators is a big reason the show’s tone has stayed consistent even as television comedy around it has shifted dramatically since 2005.
With ten new episodes of ‘It’s Always Sunny in Philadelphia’ rolling out starting tonight, the Gang has never had more room to run wild, and fans are already speculating online about which storyline, the inheritance drama or the Little League sponsorship, is going to spiral out of control first, so which plotline are you most nervous to watch play out at Paddy’s Pub?
