Alfred Lahai Gbabai Brownell (born 1965/1966) is a Liberian environmental activist and lawyer. Brownell met international attention because of his advocacy to prevent the destruction of tropical forests for palm oil production. After receiving death threats as a result of his work, he and his family fled Liberia in 2016. He won the Goldman Environmental Prize, also called the "Green Nobel," in 2019 for his work protecting more than 500,000 acres (2,000 km2) of the tropical forest that were traditional lands of local communities.
