Montgomery Scott, or "Scotty", is a character in the original Star Trek series and the films which followed. He was played by the late Irish-Canadian actor James Montgomery Doohan. Scotty's first name of Montgomery was a choice given to Doohan himself; Doohan chose the name “in honour of my grandfather, my mother’s father, James Montgomery.

He was cast as the Enterprise engineer for the second Star Trek pilot, "Where No Man Has Gone Before." He tried a variety of accents for the part, and decided to use a Scottish accent on the basis that he thought Scottish people make the best engineers.[citation needed]

Scotty will be portrayed by Simon Pegg in J.J. Abrams' upcoming Star Trek film.
