Princess Louise Margaret of Prussia, later Duchess of Connaught and Strathearn, was a member of the House of Hohenzollern who married into the British royal family. She served as the viceregal consort of Canada while her husband, Prince Arthur, Duke of Connaught and Strathearn, served as the governor general, from 1911 to 1916.

The viceregal consort of Canada is the spouse of the serving governor general of Canada, assisting the viceroy with ceremonial and charitable work, accompanying him or her to official state occasions, and occasionally undertaking philanthropic work of their own. As the host/hostess of the royal and viceroyal residence in Ottawa, the consort, if female, is also known as the chatelaine of Rideau Hall. This individual, who ranks third in the Canadian order of precedence, after the Canadian monarch and the governor general, is addressed as His or Her Excellency while their spouse is in office, and is made ex officio an Extraordinary Companion of the Order of Canada and a Knight or Dame of Justice of the Most Venerable Order of the Hospital of Saint John of Jerusalem.
