Dana Alix Zzyym[1] (born 1958) is an intersex activist and veteran of the U.S.

[2] After the culmination of a six-year legal battle, they became the first U.S. citizen to receive an official U.S. passport with an "X" sex/gender marker.

Zzyym has expressed that their childhood as a military brat made it out of the question for them to be associated with the queer community as a youth due to the prevalence of homophobia in the armed forces.

[8] In light of the State Department's continuing refusal to recognize an appropriate gender marker, on June 27, 2017, a federal court granted Lambda Legal's motion to reopen the case.

[9][10] On September 19, 2018, the United States District Court for the District of Colorado enjoined the U.S. Department of State from relying upon its binary-only gender marker policy to withhold the requested passport.
