John Clifford Watwood (August 17, 1905 – March 1, 1980), nicknamed "Lefty", was an American professional baseball outfielder in Major League Baseball, playing mainly at center field for three different teams between the 1929 and 1939 seasons.

A strong-armed outfielder and basically a line-drive hitter, Watwood entered the majors in April 1929 with the Chicago White Sox, playing for them until April 1932 before joining the Boston Red Sox (1932–1933) and Philadelphia Phillies (1939).

[1] His most productive season came with the 1930 White Sox, when he posted career-highs in games (133), batting average (.382), runs (75), RBI (51), extrabases (31) and on-base percentage (.382).

In 1931 Watwood hit .283 in 128 games for Chicago, and later was sent to the Red Sox in a five-player transaction that included teammates OF Smead Jolley and C Bennie Tate in exchange for C Charlie Berry and OF Jack Rothrock.

While in Boston, he served as a backup for Jolley (LF), Tom Oliver (CF) and Roy Johnson (RF).
