Robert Edward Belloir (July 13, 1948 – November 13, 2023) was an American professional baseball player.

Born in Heidelberg, Germany, he was the 25th German-born player in Major League Baseball.

[1] Upon returning to baseball, he was the player to be named later in the deal that sent Blue Moon Odom and a player to be named later to the Atlanta Braves (for whom Belloir had worked as a stadium usher before signing with the Indians)[2] for Roric Harrison midway through the 1975 season.

Belloir received his first call to the majors when a broken thumb sidelined Braves second baseman Marty Perez.

He made his major-league debut on August 2 and fouled out pinch hitting for pitcher Max León in his only at-bat.
