Edward Stephen "Doc" Farrell (December 26, 1901 – December 20, 1966) was an American infielder in Major League Baseball, playing mainly as a shortstop between 1925 and 1935 for the New York Giants (1925–1927, 1929), Boston Braves (1927–1929), St. Louis Cardinals (1930), Chicago Cubs (1930), New York Yankees (1932–1933), and Boston Red Sox (1935).

Farrell was the captain of the University of Pennsylvania baseball team before signing with the New York Giants prior to the 1925 season.

A well-traveled utility, he played with six different teams in a span of nine years, including two stints for the Giants.

His most productive season came in 1927, when he posted career-highs with a .316 batting average, 92 RBI, 57 runs, and 152 games while playing three different infield positions for the Giants and Braves, being considered in the National League MVP vote at the end of the season.

Farrell died in Livingston, New Jersey, just six days shy of his 65th birthday.
