Jimmy Fallon Guests Tonight: Who Is Sitting On The Couch?

So, it's Sunday. You're probably winding down, maybe dreading Monday morning just a little bit, and wondering if you should stay up for some late-night laughs. Here’s the deal: if you are looking for jimmy fallon guests tonight, you might be a tiny bit early.

The Tonight Show basically never airs brand-new episodes on Sundays. It's a weekday gig.

But don't go clicking away just yet. The lineup for the coming week—starting tomorrow, Monday, January 19, 2026—is actually kind of insane. We are talking about a mix of hip-hop royalty, Netflix stars, and even a deep dive into some pretty heavy history.

Why Everyone Is Talking About Monday Night

If you've been living under a rock, you might have missed the buzz around A$AP Rocky. He is the headliner for Monday, January 19. He’s expected to talk about his long-awaited project, Don't Be Dumb. People have been waiting for this album for what feels like a decade. Honestly, at this point, every time he sits on a talk show couch, the internet holds its collective breath for a release date.

Joining him is Dr. Henry Louis Gates Jr. He is a legend. Basically the smartest guy in any room he walks into. He’s there to discuss his documentary, Black and Jewish America. It’s a complex, nuanced look at identity that’s getting a ton of awards buzz.

Then you’ve got the young gun, Walker Scobell.
He’s the star of Percy Jackson and the Olympians. Since the season finale is right around the corner, he’s likely going to drop some hints about what’s next for the demigods. Oh, and Ontonio Kareem is handling the stand-up comedy slot. If you haven't seen his stuff, he’s got this dry, observational style that hits different.

The Rest of the Week: Will Smith and Stranger Things

Jimmy isn't slowing down after Monday. The schedule for the rest of the week is packed.

• Tuesday, Jan 20: Will Smith is the big get. He’s promoting a documentary called Pole to Pole where he literally goes from the North Pole to the South Pole. It sounds exhausting just thinking about it. He's sharing the stage with Jennette McCurdy, who is out promoting her new book, Half His Age. Also, Josh Hart from the New York Knicks is stopping by.
• Wednesday, Jan 21: Natalie Portman arrives to talk about her animated fantasy project, ARCO. It involves time travel and some wild visuals. Charlie Heaton is also on the docket, marking one of his first major appearances since Stranger Things started wrapping up.
• Thursday, Jan 22: This is the big musical night. Louis Tomlinson is performing. Fans have been camping out for this one mentally for weeks. Anthony Anderson will be there too, talking about the Star Search revival.

What Happened to the "Heated Rivalry" Buzz?

You might have seen clips floating around TikTok of a guy named Hudson Williams. He was on the show recently and it went absolutely nuclear. Jimmy actually compared the audience’s screaming to the Beatles.

He’s the star of Heated Rivalry, which has become a massive global phenomenon. While he’s not on the schedule for tonight specifically, the "Fallon Effect" is real. Jimmy’s been publicly campaigning for Hudson to host Saturday Night Live. It’s rare to see a guest have that much chemistry with Jimmy, and that’s saying something considering Jimmy laughs at almost everything.

Catching Up on the Week

Since there’s no new show tonight, it’s actually a great time to catch up on the stuff you missed.

Last week was pretty stacked. Ben Affleck and Matt Damon did a bit where they tried to name every town in Massachusetts. It was peak "Boston energy." Jason Momoa also stopped by to talk about Minecraft 2, which—let’s be real—looks weird but interesting.

If you're looking to watch, you've got options. You can catch the reruns on NBC's website, or just head to YouTube. The "Tonight Show" YouTube channel usually cuts the best bits into 10-minute segments so you don't have to sit through the commercials.

How to Watch and What to Do Next

Since there isn't a new episode tonight, January 18, you should prepare for the A$AP Rocky episode tomorrow.

Pro Tip: If you’re trying to see Louis Tomlinson on Thursday, set your DVR now. His fans tend to break the internet (and sometimes the NBC streaming app) when he performs.

Keep an eye on the official Tonight Show social media accounts around 4:00 PM EST tomorrow. They often drop "Web Exclusive" clips or behind-the-scenes photos of the guests arriving in their "tunnel fits." It’s a whole thing now.
