Fulhadhoo (Dhivehi: ފުޅަދޫ) is one of the inhabited islands of Southern Maalhosmadulhu Atoll, code letter "Baa", in Maldives.

The island is 101.21 km (63 mi; 55 nmi) northwest of the country's capital, Malé.

[2] This island lies in a small separate atoll along with Goidhu and Fehendhu, as well as four smaller uninhabited islets [1].

This atoll is oval in shape and small, its greatest length being 16 km (10 mi).

In the Admiralty Charts, this atoll is named after James Horsburgh, hydrographer to the East India Company and author of the "Directions for Sailing to and from the East Indies, China, New Holland, Cape of Good Hope, and the interjacent Ports, compiled chiefly from original Journals and Observations made during 21 years' experience in navigating those Seas".
