Clela Ann Rorex (July 23, 1943 – June 19, 2022) was an American county clerk who issued the first same-sex marriage license in the United States.

[1] Serving as the Boulder County Clerk, Rorex issued a marriage license to a gay couple in 1975 after receiving approval from the District Attorney.

[1] In December 2024, it was reported that the building that conducted the first marriage license to a same-sex couple by Rorex became officially a national monument.

"[4][7] After Rorex inquired into the legality of issuing the license, District Attorney Alex Hunter and first assistant DA Bill Wise[8] wrote an opinion stating that Colorado law did not specify whether marriage must be between a man and a woman.

[1] The Boulder County Courthouse was added to the National Register of Historic Places in part because of the marriage licenses Rorex issued.

[11][12] In June 2018, Boulder replaced an image of Roswell "Ross" Howard and his horse, Dolly, with a photo of Rorex.
