Cynthia Robinson (January 12, 1944 – November 23, 2015) was an American musician, best known for being a founding member of Sly and the Family Stone, for which she was the trumpeter and a vocalist.

Unhappy, she asked a fellow student, whom she had heard playing the trumpet in a practice room, if she could give his instrument a try.

“Everything I blew was off key, but I knew it could sound good if you worked on it, and that’s what I wanted to do,” she told the online magazine Rookie in 2013.

Robinson was among the first female trumpeters in a major American band, and the first such player in the Rock and Roll Hall of Fame.

They fell apart quickly, though, and she became a fixture of the Family Stone – a group whose members were male and female and represented different races, a novel idea at the time – alongside her cousin Larry Graham.
