John Joseph McCarthy (April 25, 1934 – May 9, 2020) was an American basketball player and coach.

He played a total of six seasons in the National Basketball Association (NBA)—two for the Royals, three for the St. Louis Hawks, and one for the Boston Celtics.

McCarthy is the first of only four players in NBA history to record a triple-double in his playoff debut, with 13 points, 11 rebounds and 11 assists against the Minneapolis Lakers on March 16, 1960; he was later joined by Magic Johnson in 1980, LeBron James in 2006 and Nikola Jokić in 2019.

McCarthy later coached the Buffalo Braves, his hometown team, for part of a season.
