Women's Declaration International

The Women's Declaration International (WDI), formerly the Women's Human Rights Campaign (WHRC), is an international advocacy organisation founded in the United Kingdom. WDI has published a Declaration on Women's Sex-Based Rights, and has developed model legislation to restrict transgender rights that has been used in state legislatures in the United States.

The organisation has been described as gender-critical, anti-trans, anti-LGBTQ+, anti-gender, trans-exclusionary, trans-exclusionary radical feminist (TERF), and as a hate group, and in several countries the group has been linked to the far right. The Southern Poverty Law Center consider it part of an "anti-LGBTQ+ pseudoscience network". The largest U.S. feminist organisation, the National Organization for Women, described WDI as "anti-trans bigots disguised as feminists." In 2025, WDI became a founding member of Women's Platform for Action International (WoPAI), an international network founded to promote "sex-based rights" and oppose what they call a "pro-gender movement," a "queer agenda," and the concept of gender identity.
