Author and Activist


“Hida Viloria, a voluble hermaphrodite with exquisite cheekbones, can pass effortlessly from ravishing femininity to sullen machismo. Having lived credibly as a woman and as a man, Hida… now seems happiest occupying ‘the middle ground’ between them.” — The New York Times

“…a woman determined to change the way people with ambiguous gender are treated.”
Barbara Walters on Hida Viloria


Hi all!

My name is Hida (pronounced “Heeda”) Viloria, and I’m a queer intersex Latinx (i.e, Latin American ethnicity and non-binary gender identity) writer, author, consultant and human rights activist. People often ask about pronouns these days, so I’ll share that I currently use “s/he” and “he/r” pronouns (pronounced “she” and “her”) for official purposes and in print, in order to acknowledge both my upbringing and identity as a woman and my lived experience in a visually non-binary intersex body, which in my case also gives me a non-binary identity as neither male nor female. I’m also gender-fluid (someone whose gender identity and/or expression shifts over time) and have used different pronouns over the years–in chronological order: she, he, ze, s/he and sometimes, most recently, they/them. As long as people are being respectful and not using pronouns to attempt to insult me (as transphobic people often do to our trans siblings), I’m not insulted by any pronoun as I believe all genders are beautiful and have identified with them all.

I also use “human rights” intentionally these days, instead of “intersex and non-binary” or “LGBTQIA” rights, because the ethnicity and race equation is often left out of this activism, yet it is central to my being and I cannot exclude it. My introduction to activism was in working for equal rights for people of color, and I continue to actively support this issue. I believe we must fight for equality for all communities–which means not prioritizing the most privileged voices over the voices and work of marginalized sub-communities within movements–or else we are not actually fighting for equality at all.

These days, I mainly using writing as a tool for my activism. You can click to see my full bibliography.

Hida is also a gender-fluid, non-binary pioneer, speaking about being both and neither male nor female in  Gendernauts (1999), and stating on Oprah in 2007 that s/he is “both” and that non-binary people shouldn’t be forced to choose between being men or women. Viloria became the recipient of the nation’s second intersex birth certificate in April 2017.

In 2010, after garnering international support for South African track star Caster Semenya, who was banned from competition on suspicion of being intersex, Viloria served, by invitation, as the sole intersex representative at the International Olympic Committee’s meeting of experts in Lausanne, Switzerland.  S/he successfully argued against the pathologization of intersex people through the use of the stigmatizing label Disorders of Sex Development (DSD) and joined in the multiple voices lobbying for the full inclusion of intersex female athletes– without mandatory, medically unnecessary “feminizing treatments”–in competitive sport.

On Human Rights Day, 2012, s/he spearheaded the the first global demand for human rights by and for intersex people, as author of an open letter to the UN High Commissioner for Human Rights, signed by over 30 international intersex organizations.

In 2013, Viloria created the resource Your Beautiful Child: Information for Parentsa one of a kind resource for parents of intersex infants which uses positive, non-stigmatizing language, and was selected and served as one of three intersex co-organizers of the Third International Intersex Forum, in Malta. The event culminated with the creation of the Public Statement of the Third International Intersex Forum, a.k.a the Malta Declaration, a consensus statement of human rights demands by the intersex community.

On Human Rights Day 2013, December 10th, Hida’s pioneering human rights advocacy work was recognized with the honor of becoming the first openly intersex person to speak, by invitation, at the United Nations Headquarters in New York, for the event Sports Comes Out Against Homophobia with fellow “out” pioneers Martina Navratilova and Jason Collins.

Throughout 2014-2016, Viloria continued to educate and advocate for intersex and non-binary people as a writer, lecturer and consultant. S/he was published widely online and in the books The Human Agenda: Conversations about Sexual Orientation & Gender Identity and the college freshman curriculum textbook Queer: A Reader for Writers, by Oxford University Press, and appeared in videos for Gender Talents, a web-based project that engages movements and discourses for gender self-determination within trans and intersex communities, and for the UN Free & Equal Campaign, in the video “What Does It Mean To Be Intersex?”

As E.D. of OII-USA, s/he educated Lambda Legal, the representatives in Intersex Campaign for Equality Associate Director Dana Zzyym’s historic lawsuit for federal gender recognition of a non-binary person on their passport. Viloria was also featured in the U.N.’s Intersex Awareness Day 2016 Campaign. In April 2017, s/he joined the movement for third gender/non-binary legal gender recognition, in a personal capacity, by becoming the second American recipient of an intersex birth certificate.
