Edmund Mortimer McDonald (September 29, 1825 – May 25, 1874) was a Nova Scotia journalist, publisher and political figure.
He represented Lunenburg in the House of Commons of Canada as an Anti-Confederate and then a Liberal-Conservative from 1868 to 1872.
In 1863, he founded the Halifax Citizen with William Garvie; the paper favoured a maritime union but opposed Confederation.
McDonald and Garvie also helped found the Anti-confederation League, which had the same aims.
