Moosup is a village and census-designated place (CDP) in the town of Plainfield, Connecticut, in the United States.

The town was established in 1689 a little more than a decade after Maussup's death at the hands of Mohawks.

Moosup is the childhood home of Major League Baseball (MLB) player Walt Dropo (January 30, 1923 – December 17, 2010).

Dropo's parents emigrated from Mostar, Yugoslavia (now Bosnia and Herzegovina), to start a new life.

His father, Savo, worked at the local textile mill while also running their Connecticut family farm.
