Henry Alexander "Heinie" Stafford (November 1, 1891 – January 29, 1972) was an American Major League Baseball player who played a single game for the New York Giants in 1916.

After a short stint in the minors, where he played as a left fielder and shortstop, the Giants called Stafford up to the big leagues at the end of the 1916 season.

Stafford saved a letter McGraw sent offering "to take you south with me and give you a thorough spring schooling in base ball."

McGraw opined that there was "enough promise to you to make me positive that it is worth your while" and cautioned Stafford against "wasting a first class opportunity.

Stafford returned to baseball briefly during World War I, playing in the industrial leagues where his wartime teammates included Chief Bender and Home Run Baker.
