Phuket formerly known as Thalang (Tha-Laang) and, in Western sources, Junk Ceylon (a corruption of the Malay Tanjung Salang, i.e. "Cape Salang"),is one of the southern provinces (changwat) of Thailand. Neighbouring provinces are (from north clockwise) Phang Nga and Krabi, but as Phuket is an island it has no land boundaries. Phuket is Thailand's largest island. It is 48 km in length, 21 km at its widest, and is in Southern Thailand, on the west-facing Andaman Sea coastline, suspended from the southern tip of Phang Nga Province by a pair of short but substantial road bridges.
