Dennis John Maruk (born November 17, 1955) is a Canadian former professional ice hockey player.

He played in the National Hockey League (NHL) from 1975 to 1989, scoring a career-high 60 goals for the Washington Capitals in 1981–82.

Maruk's rights were later obtained by the Minnesota North Stars after the Barons merged with them in 1978, but he was traded shortly afterwards to the Washington Capitals.

[citation needed] In 1982–83, Maruk was one of the players instrumental in leading the Capitals to their first playoff appearance.

Maruk was also the last Minnesota North Stars player to wear the number 9 prior to Mike Modano.
