Picard Island (also known as West Island) is an island in the Seychelles. It is the third largest island of the Aldabra Atoll in the Aldabra Group of islands, 1000 kilometres southwest of the country's capital, Victoria. The island covers an area of 9.4 km².

This island forms the northwestern edge of the Aldabra atoll. It is separated from Grand Terre (South) Island in the south by the Passe Femme channel, which contains several small islands, and from Polymnieli Island in the west by Grand Passe. The atoll's only habitation is a scientific base on Picard Island, which is only occupied for three months of each year.
