The youngest person to ever win a Nobel Peace Prize was Rigoberta Menchu Tum.

Explanation:

Rigoberta Menchu Tum is a Guatemalan indigenous leader, a member of the Maya Quiche group, a human rights defender, UNESCO goodwill ambassador and winner of the Nobel Peace Prize in 1992.

The Nobel Prize was awarded in recognition of "her struggle for social justice and ethnocultural reconciliation based on respect for the rights of indigenous people", coinciding with the fifth centenary of the arrival of Christopher Columbus to America, and with the 1992 declaration as International Year of Indian Peoples. With the resources she received from the award, she established the Rigoberta Menchu Tum Foundation, based in Guatemala; a subsidiary in Mexico, under the legal figure of Private Assistance Institution (IAP) and another in New York.  

In the reading of the prize, she claimed the historical rights denied to the natives and denounced the persecution suffered since the arrival of the Europeans, at which time she concluded a civilization developed in all areas of knowledge; she reflected the need for demilitarization and social justice in Guatemala, as well as respect for nature and equality for women.

She was mentioned in the Guinness Book of Records for being the youngest Nobel winner and being the first indigenous to win that prize.
