Michigander and Michiganian are demonyms for residents of the U.S. state of Michigan. Less common alternatives include Michiganer, Michiganite, Michiganese, and Michigine. There is no "official" term. While previous governors Jennifer Granholm, John Engler, and Jim Blanchard used Michiganian, current governor Rick Snyder uses Michigander. A 2011 poll indicated 58% of Michigan residents preferred Michigander, compared to 12% for Michiganian, with similar percentages having no preference and not liking either term. Residents of the Upper Peninsula typically refer to themselves as Yoopers instead.

Michiganian has a long history. It is the term used for the state's citizens in The Collections of the Michigan Pioneer and Historical Society since the 1870s.

Michigander is considered pejorative by some due to the circumstances under which the term was coined, but others perceive no such negative connotation. Michigander is attributed to Abraham Lincoln, coining it when he was a Whig representative in Congress. On July 27, 1848, Lincoln made a speech against Lewis Cass, who had been a long-time governor of the Michigan Territory. Cass was then running for president on a "popular sovereignty" platform that would have let states that were conquered in the Mexican-American War decide whether to legalize slavery. Lincoln accused the Democrats of campaigning on the former President Andrew Jackson's coattails by exaggerating their military accomplishments.
