Fonda passed away peacefully on Friday morning at his home in Los Angeles surrounded by family. The official cause of death was respiratory failure due to lung cancer.
“In one of the saddest moments of our lives, we are not able to find the appropriate words to express the pain in our hearts. As we grieve, we ask that you respect our privacy," the family said in a statement, according to the spokeswoman.
"And, while we mourn the loss of this sweet and gracious man, we also wish for all to celebrate his indomitable spirit and love of life."
Fonda was born in New York City, to legendary screen star Henry Fonda and New York socialite Frances Seymour Brokaw, according to the Internet Movie Database. He is the brother of actress Jane Fonda.
He gained fame in the 1969 anti-establishment film "Easy Rider" alongside Dennis Hopper and Jack Nicholson, which saw the trio embark on a drug-fuelled motorcycle road trip through the States.
Fonda produced and co-scripted the film and was nominated for an Academy Award for best original screenplay.
As a director, Fonda made a name for himself with productions such as "The Hired Hand" (1971).
He was nominated for a best actor Oscar award for "Ulee's Gold" (1998).
