John William "Moose" Clabaugh (November 13, 1901 – July 11, 1984) was an American professional baseball outfielder. He was batting star in minor league baseball who in 1926 blasted 62 home runs in a low-level circuit, and received an abbreviated trial with the Brooklyn Robins of the National League in the closing weeks of that season. But, hampered by defensive deficiencies as an outfielder, he appeared in only 11 Major League games, made one hit in 14 at bats, and returned to the minors for the remainder of his 16-season career.
