Charlesia Alexis (September 8, 1934 – December 16, 2012) was a Chagossian singer and activist, notable for helping establish the Chagos Refugee Group.
Alexis and her family went to Port Louis on Mauritius in 1967 to get medical treatment for her husband.
They were not permitted to return home afterwards because the United States wished to establish a military base in the archipelago.
In 1982, the British government paid compensation to the exiled Chagossians.
With Lisette Talate and Rita Bancoult, she established the Chagos Refugees Group in 1983.
