Per Henrik Magnus Larsson (Swedish pronunciation: [ˈmaŋnʉs ˈlɑːʂɔn]; born 25 March 1970) is a former professional tennis player from Sweden.

Larsson also reached the semi-finals of the 1994 French Open, and was part of the Swedish team which won the 1994 Davis Cup.

He won singles rubbers in the Davis Cup final in Moscow in December against both Yevgeny Kafelnikov and Alexander Volkov, as Sweden defeated Russia, 4–1.

He was runner-up in the men's doubles at the French Open that year (partnering Nicklas Kulti).

And again he won both his singles rubbers – against Pete Sampras and Michael Chang – and was on the winning team as Sweden thrashed the United States 5–0.
