Ole Hanson (January 6, 1874 – July 6, 1940) was an American politician who served as mayor of Seattle, Washington from 1918 to 1919.
Hanson became a national figure promoting law and order when he took a hardline position during the 1919 Seattle General Strike.
He then resigned as mayor, wrote a book, and toured the lecture circuit, earning tens of thousands of dollars in honoraria lecturing to conservative civic groups about his experiences and views, promoting opposition to labor unions and Bolshevism.
Hanson later left Washington and founded the city of San Clemente, California in 1925.
