Robert Patrick Lalonde - Born March 27, 1951 in Montreal, Quebec, is a retired professional Ice Hockey player.
Lalonde's amateur career began with the Ontario Hockey Association's Montreal Junior Canadiens, for whom he played from 1968 to 1971, earning 255 points in combined goals and assists. The Junior Canadiens won the Memorial Cup twice during Lalonde's tenure there, once in 1969 and again the following year.
Lalonde turned pro in 1971, joining the National Hockey League's Vancouver Canucks as their number two draft choice. He netted 1 goal and 5 assists in 27 games with the Canucks prior to being sent to their American Hockey League affiliate Rochester Americans for the remainder of the season. Lalonde skated with the Americans for 42 games, tallying 25 points in goals and assists.
The following season Lalonde skated with the Canucks, where he remained until 1977. He spent nearly half of the 1973–74 season out of play due to an ankle injury. During the 1975–76 and 1976–77 seasons, Lalonde briefly played for the Central Hockey League's Tulsa Oilers. All told, Lalonde netted 189 points in combined goals and assists in 353 games with the Canucks.
In October 1977, Lalonde (then a free agent) was picked up by the Atlanta Flames. Lalonde remained with the Flames through 1979, scoring 38 goals and 56 assists in 154 games.
Lalonde was traded to the Boston Bruins in exchange for future considerations in October 1979. He found himself playing for Fred Creighton, who had coached him previously in Atlanta. He spent the bulk of the 1979–80 and 1980–81 seasons in Boston, tallying 14 goals and 37 assists in 133 games.
In October 1981, the Bruins bought out the remaining year of Lalonde's contract and released him as a free agent. Lalonde returned to the NHL on a minor-league contract with the Calgary Flames, playing 19 games with the CHL's Oklahoma City Stars and 1 game with the Flames. He then moved to the European leagues, playing 15 games with HC Davos of the Swiss National League A before retiring from professional hockey in 1982.
