Elmo Alexander Plaskett (June 27, 1938 – November 2, 1998) was a professional baseball player from the United States Virgin Islands.

Born in Frederiksted, Saint Croix, Plaskett stood 5 feet 10 inches (1.78 m) tall and was listed at 195 pounds (88 kg); he threw and batted right-handed.

Recalled by Pittsburgh that September, he went hitless in his first two appearances, which came as a pinch hitter; but in his third game, September 17 against the San Francisco Giants, he slugged a three-run homer, the winning blow in a 5–2 Pittsburgh triumph at Forbes Field; as the starting catcher, he handled Tom Sturdivant's complete game.

Coming out of spring training in 1963, he made the Bucs' 28-man early-season squad and got into ten games, with three starts at catcher.

[2] In retirement he briefly scouted for the Pirates, and remained integrally involved in youth baseball in his native USVI[2] until his death at age 60 in Christiansted.
