Harold Warren Moon (born November 18, 1956) is a former American and Canadian football quarterback who played professionally for 23 seasons. He spent the majority of his career with the Houston Oilers of the National Football League (NFL) and the Edmonton Eskimos of the Canadian Football League (CFL). Moon also played for the Minnesota Vikings, Seattle Seahawks, and Kansas City Chiefs in the NFL. He is currently the color commentator for the Seahawks radio network, alongside Steve Raible.

Moon began his professional career with the Eskimos in 1978, after going unselected in the NFL Draft. His success during his six seasons in the CFL led him to the NFL in 1984 with the Oilers. Over his 17 NFL seasons, Moon was named to nine Pro Bowls and made seven playoff appearances. Following ten seasons with the Oilers, he had brief multiple-year stints with the Vikings, Seahawks, and Chiefs before retiring at age 44.

At the time of his retirement, Moon held several all-time professional gridiron football passing records. He was less successful in the NFL postseason, never advancing beyond the division round of the playoffs, although he won five Grey Cups in the CFL. Moon was inducted into the Pro Football Hall of Fame in 2006, becoming the first African-American quarterback and the first undrafted quarterback to receive the honor.
