Richard John Baker v. Gerald R. Nelson, 291 Minn. 310, 191 N.W.2d 185 (1971), was a case in which the Minnesota Supreme Court decided that construing a marriage statute to restrict marriage licenses to persons of the opposite sex "does not offend" the U.S. Constitution. Baker appealed the decision, and on October 10, 1972, the U.S. Supreme Court dismissed the appeal "for want of a substantial federal question".

The Minnesota Supreme Court is the highest court in the U.S. state of Minnesota. The court hears cases in the Supreme Court chamber in the Minnesota State Capitol or in the nearby Minnesota Judicial Center.
