Nicolasa Machaca Alejandro (born 1952) is a Bolivian union leader and health care worker.
A child of indigenous Quechua farmworkers, Machaca learned to read and became a literacy advocate. She coordinated community aid efforts and worked to empower women through forming mothers' clubs.[1] In 1980, she was involved in the founding of the Bartolina Sisa Confederation, the primary union organization of peasant women in Bolivia.[2] Later that year, she was imprisoned and tortured for her social activism, and she was forced to flee the country.[3] After a stay in Cuba, she returned to Bolivia and studied to become a paramedic.[4]
In 2005, she was nominated for a Nobel Peace Prize as part of PeaceWomen Across the Globe's initiative to nominate a group of 1,000 women for that year's honor.[5]
