Ronald William Plumb (born July 17, 1950) is a Canadian former professional ice hockey defenceman.
After two seasons with their Central Hockey League farm club Oklahoma City Blazers, the Bruins protected him in the June, 1972 expansion draft.
But with little chance to play with the veteran-laden NHL team, he jumped to the unproven World Hockey Association Philadelphia Blazers only weeks later.
Plumb then played for the San Diego Mariners in 1975, the Cincinnati Stingers for the following three seasons, and the New England Whalers.
Plumb followed his North American pro career with three seasons in Europe, 1983 with ERC Freiburg in the 2.Bundesliga, then 1984–1986 with the Fife Flyers in the British Hockey League.
