Family friend Alex Hitz said Hopper died at his Los Angeles home, surrounded by family and friends.
The actor and director's memorable career included the 1969 hit Easy Rider.
Hopper's rollercoaster career also included Rebel Without A Cause, Blue Velvet and Apocalypse Now.
But the improbable success of the 1969 hippie-biker epic Easy Rider remained his biggest triumph. He not only co-starred but directed and co-wrote the film, which also starred Peter Fonda and Jack Nicholson.
Hopper, Fonda and Terry Southern were nominated for Oscars for best screenplay.
