Edward Joseph "Eddie" Johnston (born November 23, 1935 in Montreal, Quebec) is a former player and coach in the National Hockey League.

Johnston grew up in an anglophone neighborhood in Montreal and was often called "E.J.", a nickname that is still often used today. He became interested in ice hockey ad a youth and became a goaltender.

He began his hockey career as a teenager in 1953 playing for the hometown Montreal Junior Royals of the Quebec Junior Hockey League. He also played for several other junior and minor league teams before joining up with the Spokane Comets of the WHL in 1961.

On June 6, 1962, he was drafted by the Boston Bruins. In his first season of action (1962-3), he became the last NHL goaltender to play every minute of every game. He was also one of the last NHL goalies to play without a facemask not adopting one until 1965 when he was hit in the face by a puck during a warm up. He later shared goaltending duties with Gerry Cheevers and helped lead the Bruins to two Stanley Cup championships in 1969-70 and 1971-2.

He was traded to the Toronto Maple Leafs in 1973 and was dealt to the St. Louis Blues a year later. He spent three years with the Blues before jouning the Chicago Blackhawks for one season. Johnston retired in 1978.

His 236 NHL career victories and 32 shutouts rank him among the league's all time goaltending leaders.

Johnston was always interested in becoming a coach and began looking for a position. He served as head coach of the Chicago Blackhawks during the 1979-80 season compiling a 34-27-19 record. The following year, he became head coach of the Pittsburgh Penguins, holding that position until July 20, 1983. He had been appointed the general manager of the Pens in May 1983 and resigned to focus on that position. He held the GM post at Pittsburgh for five years. Johnston oversaw Pittsburgh's 1984 NHL Entry Draft picks in which the Pens snagged future Hall of Famer Mario Lemieux. Johnston resisted numerous lucrative trade offers for the coveted number one draft pick that year instead opting for the promising but untested rookie.

After Johnston left the Penguins for the first time in 1988, he serve as the general manager of the Hartford Whalers from 1989 until he was released in 1992 after posting a poor playoff record.

He was once again hired as head coach of the Pittsburgh Penguins in 1993 and guided the Pens until 1997, when he was asked to step down after the Penguins failed to win a third Stanley Cup under his reign. He was offered a front office position with the Penguins and remains associated with the club.
