The actor, who shot to fame with "Titanic", was presented the Platinum Award at the 20th Santa Barbara International Film Festival in recognition of his "exceptional career", said imdb.com.
DiCaprio was quoted as saying: "It's a lifetime achievement award, which is completely and utterly surreal, given I'm only 30 years old.
"But, you know, what has it been? Almost 17 years now. I've done quite a few films. This is what I really love doing. It's what I want to do."
DiCaprio, who once appeared in the soap opera "Santa Barbara", made his first film "Critters 3" in 1991.
