Steven Mark Christoff (born January 23, 1958) is an American former professional ice hockey forward who played 248 regular season games in the NHL with the Minnesota North Stars, Calgary Flames, and Los Angeles Kings in 1980–84.

In what turned out to be his last collegiate game on March 23, 1979, Christoff scored a goal and earned an assist to help Minnesota win its third NCAA title in school history with a 4-3 victory over North Dakota.

The next year, he suited up for 56 games, netting 26 goals and 39 points and was one of the Stars' best performers as Minnesota lost the 1981 Stanley Cup finals to the New York Islanders.

Although he was an extremely popular figure in Minnesota, Christoff was traded to the Calgary Flames for the 1982–83 season, but he was used in just 45 games, scoring nine goals and 17 points.

In the 1981 TV movie about the gold medal-winning hockey team entitled Miracle on Ice, Christoff's character is played by Rick Rockwell, but is not listed in the film's credits.
