Henry Sidambarom (5 July 1863 – 15 September 1952) was a Justice of the Peace and defender of the cause of Indian workers in Guadaloupe. He was born in Capesterre-Belle-Eau, Guadeloupe, and was a Guadeloupean of Indian origin.
In 1884, he was employed at the head office of Indian immigration to Basse-Terre. In 1904, he filed a lawsuit, demanding French citizenship for the Indians of Guadeloupe. The trial of this suit lasted from 23 February 1904 until April 1923 - almost 20 years - but he won.
In 1948, the City Council and the General Council of Capesterre Belle Eau asked the French government to award Sidambarom the Legion of Honour.
In 2013, the Félix Eboué Prize was dedicated on the 150th anniversary of his birth. In December 2013, the Indian ambassador to France, Arun Kumar Singh, visited Guadeloupe for commemoration of the 150th anniversary of Henri Sidambarom's birth.
