Not drafted by a National Hockey League (NHL) team, Meagher's playing career began with the Boston University Terriers. He played four seasons at Boston University, winning numerous awards, including being named to both the First and Second All-Star teams twice. Meagher was named to the NCAA East All-American team three times, and also was placed on the NCAA Championship All-Tournament Team.

In 1977–78, Meagher was signed by the Montreal Canadiens as a free agent. He spent the first three years in the American Hockey League (AHL) with the Nova Scotia Voyageurs. In 1979–80, Meagher played for the first time in the NHL, playing a total of two games for the Canadiens. The following season, Meagher was traded to the Hartford Whalers. With Hartford, he recorded 17 points in 27 games, but still played most of the season with their AHL affiliate, the Binghamton Whalers. The 1981–82 season had Meagher playing full-time in the NHL, recording 24 goals while centering a line with Don Nachbaur and Warren Miller. In 1982–83, Meagher played in only four games with the Whalers before being traded to the New Jersey Devils. Meagher played three seasons with New Jersey, until 1984–85, when he was traded to the St. Louis Blues.

It was in St. Louis that Meagher had his most productive years, playing on a line with star Bernie Federko. He was a two-way forward and a top penalty killer in the league. In 1989–90, a season in which he was also named team captain of the Blues, Meagher received the Frank J. Selke Trophy as the league's top defensive forward. After 1990–91, Meagher retired due to injuries.
