The 1970–71 St. Louis Blues season was the St. Louis Blues' fourth season in the National Hockey League (NHL). The Blues began the 1970–71 season with high hopes after making a trip to the Stanley Cup Finals in the 1969–70 season. They purchased Christian Bordeleau from the Montreal Canadiens, who led the team in scoring and finished in the top five in game winning goals that season. They also sold Hall-of-Famer Jacques Plante to the Toronto Maple Leafs. During this season the Blues saw the most ties in their history (19), as well as most home ties (9), and the fewest home losses (7).
