John Peter Layden Jr. (December 30, 1919 – July 18, 1982) was an American two-sport professional athlete who played outfielder in Major League Baseball and an assortment of positions in football.

He was an outfielder for the St. Louis Browns and a quarterback, running back, cornerback, kick returner, punt returner, and punter for the New York Yankees of the All-America Football Conference (AAFC) and the New York Yanks of the National Football League (NFL).

He started his professional baseball career in 1946, moving up the major leagues with the St. Louis Browns for part of the 1948 season.

During that time he played with fellow former Longhorn, and future Hall of Famer, Tom Landry and helped the team to the playoffs in 1949.

[citation needed] He died in his sleep at his home at age 62, apparently from a heart attack, and is buried at the Layden Family Cemetery in Edna, Texas.
