John Trudell was a Native American author, poet, actor, musician, and political activist. He was the spokesperson for the Indians of All Tribes' takeover of Alcatraz beginning in 1969, broadcasting as Radio Free Alcatraz. During most of the 1970s, he served as the chairman of the American Indian Movement, based in Minneapolis, Minnesota.

The Occupation of Alcatraz was a 19-month long protest when 89 Native Americans and their supporters occupied Alcatraz Island. The protest was led by Richard Oakes, LaNada Means, and others, while John Trudell served as spokesman. The group lived on the island together until the protest was forcibly ended by the U.S. government.
