Edward Trowbridge Collins Jrwas an American professional baseball outfielder in the Major Leagues for parts of three seasons between 1939 and 1942 for the Philadelphia Athletics. His father was Baseball Hall of Fame member Eddie Collins, who is the only player in American baseball history to have 3,300+ hits in under 10,000 at-bats.

Born in the Philadelphia suburbs, the younger Collins attended the elite Episcopal Academy, graduating in the class of 1935. He went on to Yale University, where he played on the team that won the 1937 Ivy League Championships. In 1939, his senior year, Collins was team captain at Yale. Upon graduation, he signed with the Philadelphia Athletics and played 32 games his rookie year, 1939. In the 1940 season he joined the International League, playing for the Baltimore Orioles. In the 1941 season he returned to the Athletics for a career-high 80 games. Collins played 20 games for the Athletics in 1942, before entering military service with the Navy.

After the war, Collins returned to the Athletics but was released in April 1946. He went on to play in the International League for the Jersey City Giants and the Buffalo Bisons before retiring from the field. In the Major Leagues, Collins appeared in 132 games played—eighty of them during 1941—and collected 66 hits, with nine doubles and three triples. He had 16 runs batted in.

From 1947 to 1954, Collins was assistant director of the farm system for the Philadelphia Phillies, and assistant general manager of the Phillies from 1954 to 1955.

In 1955, he received a master's degree in education from Harvard University, and went on to teach at his alma mater, the Episcopal Academy, from 1960 to 1982.

Four weeks after the bombing of Pearl Harbor, Collins married Jane Pennock. She was the daughter of Hall-of-Fame pitcher Herb Pennock, who served as the general manager of the Phillies from 1944 until his sudden death in January 1948. The Collinses settled in Kennet Square, where the Pennock family had been landowners since the end of the seventeenth century. There they raised two sons, Peter and Edward Trowbridge Collins, III. After 58 years of marriage, Eddie Collins and his wife Jane died within five weeks of each other in 2000.
