Daniel Constantine Marino Jr. (born September 15, 1961) is a former American football quarterback who played seventeen seasons for the Miami Dolphins of the National Football League (NFL). The last quarterback of the quarterback class of 1983 to be taken in the first round, Marino held or currently holds dozens of NFL records associated with the quarterback position. Despite never being on a Super Bowl-winning team, he is recognized as one of the greatest quarterbacks in American football history.

Best remembered for his quick release and powerful arm, Marino helped the Dolphins become consistent postseason contenders, leading them to the playoffs ten times and one Super Bowl appearance in XIX, although a title victory ultimately eluded him during his career. Marino is considered by many to be one of the greatest players to never win a Super Bowl and has the most career victories of quarterbacks to not win a title at 155. He was inducted into the Pro Football Hall of Fame in 2005.
