Tanjong Chek Jawa (or Tanjung Chek Jawa or simply Chek Jawa) is a cape and the name of its 100-hectare wetlands located on the south-eastern tip of Pulau Ubin, an island off the north-eastern coast of the main island of Singapore. Chek Jawa is among the last few places left with a natural rocky shore.
The wetlands are unique as several ecosystems can be observed in one area — sandy beach, rocky beach, seagrass lagoon, coral rubble, mangroves and coastal forest.
In December 2001, the government called off reclamation plans of the Chek Jawa area after a biodiversity survey conducted by conservationist volunteers. State use of the land will be deferred for the next 10 years. However, Chek Jawa may still be re-used by the government in and after 2012.
