Albert Bailey "Allie" Watt (December 12, 1899 – March 15, 1968) was a Major League Baseball player who played in 1920 with the Washington Senators.

With a double in his only turn at-bat, Watt is one of the rare Major Leaguers with a career batting average of 1.000.

Watt is doubly notable because he is one of the few real players whose name is in the correct position in the famous Who's on First?

comedy routine (Watt played second base).
