John Krasinski I'm The Sexiest Man Alive!!!

John Krasinski was a big winner Tuesday ... getting anointed People magazine's 2024 Sexiest Man Alive and accepting the honor on Stephen Colbert's late-night show.

Krasinski was pictured on the cover of People wearing a T-shirt and jeans while sitting on the bumper of an NYC yellow taxi.

Beyond his good looks, John has been crushing it on the silver screen over the years, enjoying starring roles in many Hollywood films such as "A Quiet Place," "If" ... and the "Jack Ryan" TV series. And, let's not forget his big break in the TV sitcom, "The Office."

John has also been married to actress Emily Blunt for 14 years and the couple live in Brooklyn with their 2 daughters, Hazel and Violet.

Clearly, John's a solid choice to be crowned People's Sexiest Man  ... but don't tell that to Colbert.

On his show Tuesday night, Stephen seemed to think he was gonna go home with the coveted title. However, it didn't work out that way -- yet, in the end, Stephen was good-humored about it all.

John even came out onstage and sat down with Stephen to joke about his sexy biceps and beating the comedian in arm wrestling -- twice! Check out the clip ... it's funny stuff.
