William W. "Moon" Evans (c. 1908 – August 18, 1963) was an American attorney, Marine Corps officer, and athlete.

[5] In 1929, Evans was one of "the heroes of Maryland's dramatic finish" in which it tied a heavily favored 1929 Yale Bulldogs football team, 13–13.

[6] An "intricate triple pass" from Evans to Shorty Chalmers to Boze Berger scored the game's final points in the closing minutes to ensure the stalemate.

[9] In 1929, Evans scored 37 goals, which made him the nation's leading scorer,[10] and he earned that title again the following year.

[15][16] He graduated from Maryland in 1930 with a Bachelor of Arts degree,[2][15] and was voted the "Best Senior Athlete", finishing ahead of Julius J. Radice and Albert Heagy.

[2] After the war, he resigned from the military with the rank of captain, and returned to practicing law in Montgomery County, Maryland, until his death in 1963.
