The lieutenant governor of British Columbia is the representative of the monarch in the province of British Columbia, Canada. The office of lieutenant governor is an office of the Crown and serves as a representative of the monarchy in the province, rather than the governor general of Canada. The office was created in 1871 when the Colony of British Columbia joined Confederation. Since then the lieutenant governor has been the representative of the monarchy in British Columbia. Previously, between 1858 and 1863 under colonial administration the title of lieutenant governor of British Columbia was given to Richard Clement Moody as commander of the Royal Engineers, Columbia Detachment. This position coexisted with the office of governor of British Columbia served by James Douglas during that time.

In Canada, a lieutenant governor is the representative of the King of Canada in the government of each province. The Governor General of Canada appoints the lieutenant governors on the advice of the Prime Minister of Canada to carry out most of the monarch's constitutional and ceremonial duties for an unfixed period of time—known as serving "His Excellency’s pleasure"—though five years is the normal convention. Similar positions in Canada's three territories are termed "Commissioners" and are representatives of the federal government, not the monarch directly.
