John Coleman Calhoun (1869 – 1948) was a politician in Alberta, Canada and a municipal councillor in Edmonton.
Calhoun was born in 1869 in Albert County, New Brunswick, where he remained until he moved to British Columbia in 1885. He stayed there for ten years before moving to Alberta to engage in ranching and fur trading. Early in the twentieth century, he moved to Edmonton where he worked in real estate and horse trading. In 1906, he built the King Edward Hotel, which would become Edmonton's leading hotel after a 1910 expansion.
Calhoun made his first bid for elected office in the 1905 election, when finished ninth out of ten candidates for alderman. However, on May 7, 1906, John R. Boyle resigned from Edmonton City Council, and Calhoun was elected to finish his term (which ran until December of that year). He did not seek re-election, but did run in the 1907 election, once he was a year removed from office. He finished ninth of twelve, and did not re-enter politics thereafter.
