The 2012 Oregon Secretary of State election was held on November 6, 2012, to elect the Oregon Secretary of State. Incumbent Democratic Secretary of State Kate Brown ran for a second term against Republican Knute Buehler. Brown and Buehler ran against each other again in the 2018 Oregon gubernatorial election.
Oregon allows candidates to be cross-nominated by up to three political parties. The Independent Party of Oregon holds a month-long online primary to select which candidate receives their nomination. The party chose candidates in a number of legislative and local races but only one statewide race, Secretary of State.
Brown won four of five congressional districts.
