Urban Clarence "Red" Faber (September 6, 1888 – September 25, 1976) was an American right-handed pitcher in Major League Baseball from 1914 through 1933, playing his entire career for the Chicago White Sox. He was a member of the 1919 team but was not involved in the Black Sox scandal. In fact, he missed the World Series due to injury and illness.

Faber won 254 games over his 20-year career, a total which ranked 17th-highest in history upon his retirement. At the time of his retirement, he was the last legal spitballer in the American League; another legal spitballer, Burleigh Grimes, was later traded to the AL and appeared in 10 games for the Yankees in 1934. Faber was inducted into the Baseball Hall of Fame in 1964.
