Sumak Helena Sirén Gualinga (born February 27, 2002) is an Ecuadorian environmental and human rights activist from the Kichwa Sarayaku community in Pastaza, Ecuador.

[7] From a young age, Gualinga has witnessed the persecution of her family for standing against the interests of big oil companies and their environmental impact on Indigenous land.

[8] She and her family describe numerous ways in which they, as members of Indigenous communities in the Amazon, have experienced climate change, including a higher prevalence of forest fires, desertification, direct destruction and disease spread by floods, and faster melting snow on mountain peaks.

[7] Gualinga held a sign that read "sangre indígena, ni una sola gota más" (Indigenous blood, not one more drop) outside of the UN headquarters in New York City at a demonstration with hundreds other of young environmental activists during the 2019 UN Climate Action Summit.

[8] The movement's petition is to: "Demand that Patricia Espinosa, Executive Secretary to the United Nations Framework Convention on Climate Change (UNFCCC), refuse funding from fossil fuel corporations for COP26!".

On April 22, 2022, Helena Gualinga was pictured in Vogue magazine in an article on traditional Kichwa Sarayaku face paintings written by Atenea Morales de la Cruz.
