Byron Ingemar "Boss" Johnson (born Björn Ingimar Jónsson; December 10, 1890 – January 12, 1964), served as the 24th premier of British Columbia, from 1947 to 1952.

To his contemporaries he was often referred to by his nickname, Boss Johnson, which had nothing to do with his personality, but was an anglicization of the Icelandic "Bjossi", which is a diminutive form of his birth-name of Bjorn, which was adapted into English as Byron.

After overseas service in World War I, he and his brothers opened a building supplies business in Victoria, which proved to be successful.

Johnson returned to his business and in World War II was put in charge of constructing Royal Canadian Air Force facilities throughout the province.

It expanded the highway system, extended the Pacific Great Eastern Railway, and negotiated the Alcan Agreement, which facilitated construction of the Kenney Dam, the first major hydroelectric project in the province.
