Lowell Wilson MacDonald (born August 30, 1941) is a Canadian former professional National Hockey League winger who played during the 1960s and 1970s.

MacDonald broke into the NHL with the Detroit Red Wings after being promoted from the AHL's Pittsburgh Hornets. He spent parts of three seasons in the Los Angeles Kings organization but sat out most of the 1970 campaign to work on his college degree. That summer, his former coach with the Kings, Red Kelly, had been hired by the Pittsburgh Penguins and selected MacDonald In the intra-league draft. He played just 10 games for Pittsburgh before an old knee injury flared up and forced him to consider retirement. After sitting out all of the 1971–72 season, his wife, Joyce, cajoled Lowell into attempting a comeback.^[1] MacDonald made the Penguins out of training camp and went on to set new career records for goals and points. His stunning return earned MacDonald the 1973 Bill Masterton Memorial Trophy.^[2]

In 1973, MacDonald was placed on Pittsburgh's top line alongside Syl Apps Jr. and Jean Pronovost. The 'Century Line', as they would come to be known, would be the driving force for the Penguins for three seasons with MacDonald leading the team in goals in 1974. Unfortunately, his time as a star was cut short when he suffered a seventh knee injury that ended his 1977 season after just 3 games. He returned the following year for a brief stint but ended up retiring before the end of the campaign. In 506 NHL games, MacDonald recorded 180 goals, 210 assists, 390 points, and only 92 penalty minutes.

After hanging up his skates, MacDonald became the head coach at the University School of Milwaukee, a prep school in Wisconsin. Over his 18 years with the school, MacDonald compiled a 263-180-17 record and was later inducted into the Wisconsin Hockey Coaches Hall of Fame.^[3]

Two of Lowell's sons had careers involved with ice hockey. Lowell Jr. was a producer for TV broadcasts but was most noted for a controversy in 2010 that caused him to be suspended by FSN Pittsburgh.^[4] Lane had an outstanding college career that saw him win both the NCAA Championship and Hobey Baker Award while at Harvard. Unfortunately, persistent migraines forced Lane to retire in 1991.
