Pulau Ketam, literally translated, means "Crab Island". It is a small island located off the coast of Port Klang, Selangor, Malaysia, and was founded circa 1880. The island is easily accessible from the Port Klang jetty by ferry. On the island are "floating houses", perched on wooden stilts 1 to 10 metres (3 to 33 ft) above sea level.
The main thoroughfares are narrow concreted pavements, whilst in the residential areas, the older rickety wooden plank bridges can still be seen. There are no cars in Pulau Ketam, only bicycles, some of which are motorised.
Pulau Ketam is equipped with almost all the basic facilities. It also plays a role as a major fish, crabs, prawns provider to Klang valley and a tourism spot of Negeri Selangor. Ferry services are available daily. Speedboat service is available 24 hours per day on call; cargo boats are also available.
