Benjamin Lewis Crosby Jr. (March 22, 1868 – December 29, 1892) was an American college football player and coach. Born in Halcott Centre, New York, Crosby attended Yale University beginning in 1889; while there, he was a popular student and sportsman. He was a two-year starter on the football team and a backup on the crew team. During his junior year, he was replaced on the football team by freshman Frank Hinkey and never returned to a starting position. The remainder of Crosby's time at Yale was successful and he enrolled at the New York Law School after graduation.
