Louis Barrabé (15 March 1895 – 13 February 1961) was a French economic field geologist and professor who contributed to studies of the geology of Madagascar and the Caribbean Islands of Martinique and Guadeloupe.
Barrabé was born in Bonneval where his father was an amateur naturalist and member of the Linnean Society of Normandy.
He was conscripted during World War I and demobilized in 1919 as a lieutenant and awarded a Croix de Guerre.
Together they worked on the field and discovered an oil deposit at Gabian in 1924 and natural gas at Saint-Marcet in 1939.
In 1927 he was posted to Martinique and began to suffer from paralysis of the legs from which he recovered after returning to France.
