Dean Paul Martin (November 17, 1951 - March 21, 1987) was an American singer and actor.

The son of the legendary performer Dean Martin, he was a member of the pop group Dino, Desi, & Billy. "Dino" was thirteen when he, Desi Arnaz Jr., and William "Billy" Hinsche formed the trio. Oriented toward teenage girls, the group had a few minor hits between 1965 and 1968. Martin later began to go by his given name Dean Paul instead of the nickname "Dino". He became a successful tennis player and actor.

Martin met an untimely death in 1987 when his National Guard fighter jet crashed over a mountainous area of California, killing him and his co-pilot. Shortly before his death, Dean Paul Martin had starred in the TV series Misfits of Science. The singer Dean Martin never recovered from the loss of his son, and he retired from show business that same year.

Dean Paul Martin was the former husband of both actress Olivia Hussey and Olympic skating gold medalist Dorothy Hamill. Martin’s 12-year-old son by Hussey, Alex, had watched his father take off on the ill-fated flight.

He is interred in the Los Angeles National Cemetery , a former U.S. Veterans Administration cemetery in Los Angeles, California.
