Robert Thore Nystrom (born October 10, 1952) is a Canadian former professional ice hockey right winger.
He played for the New York Islanders of the National Hockey League (NHL) from 1972–86.
He is best remembered as having scored the winning goal at the 7:11 mark of overtime to give the New York Islanders the 1980 Stanley Cup title.
This signaled the first of four straight championships for the club.
He was also among the last NHL players to not wear a helmet during a game.
Playing his minor hockey in Hinton, Alberta, Nystrom is immortalized on the town's wall of fame.
He is arguably the most successful NHL player from the geographical area that yielded the likes of Dave Scatchard and Dean McAmmond.
His son Eric last played professional hockey for Norway’s Stavanger Oilers, and previously played for the Nashville Predators, Calgary Flames, Minnesota Wild, and Dallas Stars of the NHL.
