Mr. Bond died in Fort Walton Beach, Fla., after a brief illness, the center said in a statement Sunday morning.
He was one of the original leaders of the Student Nonviolent Coordinating Committee, while he was a student at Morehouse College in Atlanta.
He moved from the militancy of the student group to the top leadership of the establishmentarian N.A.A.C.P. Along the way, he was a writer, poet, television commentator, lecturer, college teacher, and persistent opponent of the stubborn remnants of white supremacy.
He also served for 20 years in the Georgia Legislature, mostly in conspicuous isolation from white colleagues who saw him as an interloper and a rabble-rouser.
Mr. Bond’s wit, cool personality and youthful face became familiar to millions of television viewers during the 1960s and 1970s. He attracted adjectives — dashing, handsome, urbane — the way some people attract money.
On the strength of his personality and quick intellect, he moved to the center of the civil rights action in Atlanta, the unofficial capital of the movement, at the height of the struggle for racial equality in the early 1960s.
Moving beyond demonstrations, he became a founder, with Morris Dees, of the Southern Poverty Law Center, a legal advocacy organization in Montgomery, Ala. Mr. Bond was its president from 1971 to 1979 and remained on its board for the rest of his life.
