Regino José Otero Gómez (September 7, 1915 – October 21, 1988) was a Cuban professional baseball player who had a long career in the minor leagues in the United States (1936–1953), and played briefly with the Chicago Cubs of Major League Baseball in 1945.

A left-handed batting first baseman, he threw right-handed, and was listed as 6 feet (1.8 m) tall and 165 pounds (75 kg).

After his playing career ended, he managed in the U.S., Cuba, Mexico and Venezuela, spent eight years (1959–1666) as a coach in the U.S. major leagues, then worked as a scout for two MLB clubs for more than a decade.

After the 1947 season, he joined the Portsmouth Cubs of the Piedmont League, where he would play for the next five years, also serving as manager in 1951–52.

In his homeland, Otero played in 480 games in the Cuban Professional League for thirteen years from 1936 to 1953.

In Major League Baseball, he served as a coach for the Cincinnati Reds (1959–1965) and Cleveland Indians (1966).
