1979–80 Chicago Black Hawks season

The 1979–80 Chicago Black Hawks season was the 54th season of operation of the Chicago Black Hawks in the National Hockey League. The club was coming off a first-place finish in the Smythe Division in the 1978-79, despite finishing with a 29-36-15 record. In the 1979 playoffs, the Black Hawks were swept by the New York Islanders in the quarter-finals.

During the off-season, the Black Hawks named Eddie Johnston as their new head coach, as Bob Pulford stepped down to focus on his general manager duties. Johnston was previously the head coach of the New Brunswick Hawks, Chicago's AHL affiliate, in 1978-79, leading the team to a 41-29-10 record. Johnston was also a former goaltender, playing in the NHL from 1962-1978, earning a 234-257-80 record with a 3.25 GAA in 592 career games while playing for the Boston Bruins, Toronto Maple Leafs, St. Louis Blues and the Chicago Black Hawks. Johnston won two Stanley Cup championships with the Bruins in 1970 and 1972.

With the NHL expanding to 21 teams, as the Edmonton Oilers, Hartford Whalers, Quebec Nordiques and Winnipeg Jets joined the league from the WHA, the Hawks remained in the Smythe Division, with the Oilers and Jets joining Chicago, Colorado Rockies, St. Louis Blues and Vancouver Canucks to form the only six team division in the league.
