Gary Allan "Gubbio" Gambucci (born September 22, 1946 in Hibbing, Minnesota) is a retired American ice hockey centre who appeared in a total of 51 National Hockey League regular season games with the Minnesota North Stars from 1971 to 1974.
Before turning professional, Gambucci excelled as a scorer for the United States national team at the 1969, 1970 and 1971 World Championships as well as the University of Minnesota men's hockey team. Gambucci was signed as a free agent by the Montreal Canadiens in the spring of 1971 after scoring seven goals in ten games for Team USA at the 1971 world championships in Berne (he was also elected to the tournament all star team at the world championship "Pool B" qualifying tournament in 1970).
The Canadiens immediately traded him and Bob Paradise to the North Stars for cash. However, Gambucci failed to become a regular in Minnesota and left the NHL for the Minnesota Fighting Saints of the rival World Hockey Association following the 1973–74 season.
Gambucci retired from professional hockey in 1976 after playing 112 WHA regular season games for the Fighting Saints as well as representing the United States at the 1976 Ice Hockey World Championships tournament in Katowice.
