Vanessa Nakate (born 15 November 1996) is a Ugandan climate justice activist. She grew up in Kampala and became a celebrity in December 2018 after becoming concerned about the unusually high temperatures in her country.

Inspired by Greta Thunberg to start her own climate movement in Uganda, Nakate began a solitary strike against inaction on the climate crisis in January 2019. For several months she was the lone protester outside of the gates of the Parliament of Uganda. Eventually, other youth began to respond to her calls on social media for others to help draw attention to the plight of the Congolian rainforests. Nakate founded the Youth for Future Africa and the likewise Africa-based Rise Up Movement.
