Sandra Harmon was an American television writer and producer, and author.

Harmon's credits as a television writer include ABC's The Dick Cavett Show from 1969-71, and Cos, a short-lived ABC comedy/variety series hosted by Bill Cosby in 1976, for which she was head writer.

She wrote and produced the 1979 NBC made-for-TV movie Fast Friends, which was based on her experiences working on Cavett's talk show. It starred Dick Shawn as a talk show host who goes berserk onstage and is replaced by a young, unknown comedian (played by David Letterman).

Harmon also produced the 1985 CBS telefilm Promises to Keep, which starred Claire Bloom and Robert Mitchum.

Harmon co-authored (with Priscilla Presley) the 1980s best-seller Elvis and Me, the story of Elvis Presley and wife Priscilla Presley. ABC turned Elvis and Me into a four-hour miniseries that attracted huge ratings when it aired in February 1988.

Harmon died December 13, 2018, in New York City, New York. She was 80.
