Stephen Colbert is scheduled to appear on Jimmy Kimmel Live on Tuesday, Sept. 15, 2026. The late-night booking falls inside the week of September 14 through September 18, a schedule says is subject to change.
Jimmy Kimmel Live at 11:35 p.m. EST
Jimmy Kimmel Live airs every weeknight at 11:35 p.m. EST, so Colbert’s slot lands in a fixed broadcast window rather than a one-off special. For viewers of Jimmy Kimmel Live and fans of Stephen Colbert, that means a specific appointment night is already on the books, even if the weekly lineup can still shift.
ABC describes Jimmy Kimmel Live as an Emmy Award-winning late-night talk show, and the week-by-week guest list gives the booking a practical edge over vague promotion. Stephen Colbert Wins Stephen Colbert Anti-censorship Award After CBS Ends The Late Show sits in the same broader late-night conversation, but this appearance is its own scheduled turn on the show’s Monday-through-Thursday run.
Monday Through Thursday Guests
Monday, Sept. 14 is set to open the week with Mariska Hargitay and Kaia Gerber, along with The Milk Carton Kids as the musical guest and Franky Perez sitting in with The Cletones. Tuesday then places Stephen Colbert alongside Medium Build and Judith Hill with The Cletones, making it the most closely watched night for viewers tracking the lineup.
Wednesday, Sept. 16 pairs Bill Burr with H.E.R. and Judith Hill with The Cletones, while Thursday, Sept. 17 brings Sarah Paulson and Rory Scovel with Dragonflies and Judith Hill with The Cletones. The schedule points to a broad late-night rotation rather than a single-theme week, which is the kind of setup that usually keeps viewers checking for changes before airtime.

The Tuesday placement matters because it is the clearest dated booking in the week, and it is the one tied to Stephen Colbert by name. If the schedule holds, that is the night viewers should plan around; if the network adjusts the week, the listed appearance can move with it.
What Stephen Colbert will appear to promote or discuss is not stated, so the value here is the booking itself. For now, the clean read is simple: Tuesday is the late-night date to watch, and the rest of the week is already built around the same 11:35 p.m. EST slot.
