Same-sex marriage in Oklahoma

Same-sex marriage in Oklahoma has been legal since October 6, 2014, following the resolution of a lawsuit challenging the state's ban on same-sex marriage. On that day, following the U.S. Supreme Court's refusal to hear an appeal in a case that found Oklahoma's ban on same-sex marriage unconstitutional, the Tenth Circuit Court of Appeals ordered the state to recognize same-sex marriage.

On January 14, 2014, Judge Terence C. Kern, of the United States District Court for the Northern District of Oklahoma, declared Question 711, which banned the recognition and performance of same-sex marriage, unconstitutional. The case, Bishop v. United States (formerly Bishop v. Oklahoma), was stayed pending appeal.

On July 18, 2014, a federal appeals court upheld a federal judge's ruling overturning Oklahoma's same-sex marriage ban. However, the appeals court put its ruling on hold pending an appeal. On October 6, 2014, the U.S. Supreme Court rejected that appeal, leaving the Tenth Circuit Court's ruling in place. The Oklahoma Government responded by implementing the circuit court's ruling, recognizing same-sex marriage in the state.
