The 43-year old Boseman died at his home in the Los Angeles area with his family by his side, his publicist Nicki Fioravante told The Associated Press.
Boseman was diagnosed with colon cancer four years ago, his family said in a statement.
“A true fighter, Chadwick persevered through it all, and brought you many of the films you have come to love so much,” his family said.
“From Marshall to Da 5 Bloods, August Wilson’s Ma Rainey’s Black Bottom and several more - all were filmed during and between countless surgeries and chemotherapy. It was the honor of his career to bring King T’Challa to life in Black Panther."
Boseman had not spoken publicly about his diagnosis.

Born in South Carolina, Boseman graduated from Howard University and had small roles in television before his first star turn in 2013. His striking portrayal of the stoic baseball star Robinson opposite Harrison Ford in 2013′s “42” drew attention in Hollywood and made him a star.
Boseman died on a day that Major League Baseball was celebrating Jackie Robinson day.
“This is a crushing blow” actor and director Jordan Peele said on Twitter, one of many expressing shock as the news spread across social media.
“This broke me,” said actor and writer Issa Rae.
His T’Challa character was first introduced to the blockbuster Marvel movies in 2016′s “Captain America: Civil War,” and his “Wakanda Forever” salute reverberated around the world after the release of “Black Panther” two years ago.
The character was last seen standing silently dressed in a black suit at Tony Stark’s funeral in last year’s "Avengers: Endgame."
Even at the outset of his Hollywood career, Boseman was clear-eyed about — and even skeptical of — the industry in which he would become an international star.
“You don’t have the same exact experience as a Black actor as you do as a white actor. You don’t have the same opportunities. That’s evident and true,” he told AP while promoting “42.” “The best way to put it is: How often do you see a movie about a black hero who has a love story — with a black woman, or any woman for that matter ... he has a spirituality. He has an intellect. It’s weird to say it, but it doesn’t happen that often.”
In addition to Robinson and Brown, Boseman portrayed U.S. Supreme Court Justice Thurgood Marshall in 2017′s “Marshall.“
He took on his first producing job in last year’s action thriller “21 Bridges,” in which he also starred, and was last seen on-screen in Spike Lee’s film “Da 5 Bloods” as the leader of a group of Black soldiers in the Vietnam War.
