Quinn R. Mallory is a fictional character on the science fiction television show Sliders, played by Jerry O'Connell.

Quinn was born in 1973 and raised in San Francisco, California, the son of Michael and Amanda Mallory. The driver's license shown in the episode "Summer of Love" indicates his birthday is January 24, but in the same episode, Wade says that Quinn is a Libra, which would put his birthday between September 23 and October 22.

Quinn was skipped ahead two grades in school at some point before 1984. He was bullied in junior high, and being skipped ahead two grades made him smaller and physically slower than his classmates. His father died in 1984. The week after his father's death, several students, including Rex Crandall, bullied Quinn at school, which ended in an incident where he hit Rex with a baseball bat. Quinn shattered Rex's kneecap, and Rex walked with a limp for the rest of his life. In the episode "The Guardian", on a world where events occurred as they did on Earth Prime twelve years ago, Quinn prevented history from repeating itself.

In "Summer of Love", Quinn confesses to Arturo that he was starting quarterback in high school (indicating that despite being slower than his classmates in junior high, he became an athlete in high school, probably driven by a in this case healthy inferiority complex). In the episode "Slide Like an Egyptian", Quinn meets his father in the afterlife while being used for life after death experiments. They discuss how they enjoyed playing American football together.
