Murphy-Gamble Limited was a long-time department store in the City of Ottawa, Ontario, Canada. The store was located at 118 Sparks Street in a 1909 building designed by C.P. Meredith, and for years used the slogan "Ottawa's Smart Store". Murphy-Gamble's fifth floor restaurant was known as the Rideau Room. Although Murphy-Gamble was an Ottawa landmark and retail institution for years, it has largely been forgotten today.
