He was best known for films including Spartacus and Ace In The Hole, and his explosive acting style and masculine persona established him as a leading man throughout the 1950s.
His son, actor Michael Douglas, confirmed his father had died on Wednesday night.
“It is with tremendous sadness that my brothers and I announce that Kirk Douglas left us today at the age of 103,” Michael’s statement said.
“To the world he was a legend, an actor from the golden age of movies who lived well into his golden years, a humanitarian whose commitment to justice and the causes he believed in set a standard for all of us to aspire to.”
Michael’s wife, Catherine Zeta Jones led the tributes to her “darling” father-in-law on Instagram.
“To my darling Kirk,” the Chicago actress wrote. “I shall love you for the rest of my life. I miss you already. Sleep tight...”
Elsewhere, the Academy of Motion Picture Arts and Sciences led the tributes, tweeting a picture of the actor from his best-known film Spartacus alongside his quote: “I wanted to be an actor ever since I was a kid in the second grade. I did a play, and my mother made a black apron, and I played a shoemaker. After the performance, [my father] gave me my first Oscar: an ice cream cone.”
They followed up with the message: “Goodbye to a Hollywood legend.”
