Keith Wright was born April 13, 1944 in Aurora, Ontario. A four-year member of the Peterborough Petes (1960-64), Wright made his professional debut in 1965 after being claimed by Omaha of the Central Professional Hockey League from Montreal in the 1964 Reverse Draft.
In his only season with Omaha, Wright recorded 35 points before being claimed by the New York Rangers in the 1965 CPHL Intra-League Draft. A member of the Rangers' organisation for only one day, Wright was claimed on waivers the very next day by the Boston Bruins before joining the CPHL's Oklahoma City Blazers for the 1965-66 season.
The 1965-66 season saw Wright and the Blazers capture the CPHL Championship as they swept the Tulsa Oilers four games to none. Shortly after the 1966-67 season began, Wright played in only ten games with Oklahoma City before joining the California Seals of the NHL.
After being claimed by the Philadelphia Flyers in the 1967 Expansion Draft and making his only appearance in the NHL during the 1967-68 season, Keith Wright was traded to the Quebec Aces of the American Hockey League where he spent the majority of the year.
Retiring for two years following the 1967-68 season, he returned to professional hockey and the Quebec Aces in 1970-71 where he split his time with the Oklahoma City Blazers of the Central Hockey League.
Stepping aside once again following the 1970-71 season, and returning to the game with the Orillia Terriers of the Ontario Hockey Association Senior "A" Hockey League in 1972-73, Wright retired permanently from the game having played in one NHL game.
