Ernie Broglio, American baseball player
Ernest Gilbert Broglio (; August 27, 1935 – July 16, 2019) was a professional baseball pitcher. He played for the St. Louis Cardinals and Chicago Cubs of Major League Baseball from 1959 to 1966.

After attending high school and junior college in his native California, Broglio signed with the independent Oakland Oaks of the Pacific Coast League. He was acquired by the New York Giants in 1956. After two seasons in the Giants’ minor league system—when he won 17 games each year—Broglio was traded to the St. Louis Cardinals in October 1958.

Although he led the National League in wins with 21 for the 1960 Cardinals and won 18 for the 1963 Redbirds, Broglio is best remembered as the "other player" in the ultimately lopsided trade that sent future Baseball Hall of Fame outfielder Lou Brock from the Chicago Cubs to the Cardinals on June 15, 1964. His career in the majors came to an end during the 1966 season. He died on July 16, 2019 from cancer.
