Louis Olivier Bancoult (born 1964) is a Chagossian activist for the right of return and the leader of the Chagos Refugee Group (CRG).

[1][2] He was born in 1964 on the island of Peros Banhos in the Chagos Archipelago, from where he was forcibly removed at the age of four and transported to Mauritius.

[3] In response, his mother Rita Élysée Bancoult, together with activists Charlesia Alexis and Lisette Talate, founded the CRG[2] in 1982.

He was one of five islanders who, on 13 February 2022, stepped on to the beach of Peros Banhos, one of the larger atolls making up the occupied Chagos Islands, due to Mauritius legal victories "first at the UN General Assembly, then at the UN's International Court of Justice, and finally at the UN's tribunal for settling maritime disputes".

[6] In 2023, he was nominated for the Nobel Peace Prize, along with Liseby Elysé, a Chagossian woman who testified before the International Court of Justice in the case opposing Mauritius to the United Kingdom.
