Hilaria Supa Huamán (born 28 December 1957) is a Peruvian politician, human rights activist, and an active member of several Indigenous women's organizations in Peru and around the world.

Hilaria Supa was raised by her grandparents on her mother Helena Huamán's side, who were peasants in a hacienda, or a big farm owned by rich families.

She became the first parliamentarian in Peru's history to take the oath in any Indigenous language, for which both were sharply criticized by Congresswoman Martha Hildebrandt and some other members of Congress.

[3][4][5] Congresswoman Hilaria Supa participated twice at the United Nations Permanent Forum on Indigenous Issues, where she denounced the crisis that her community was facing, after the Alan García administration passed free trade policies and abusive decrees in complicity with the U.S. government.

While congressmen of the American Popular Revolutionary Alliance (APRA) and the Fujimori parties were criticizing this, she received support by Peruvian education experts.
