Pulau Tekong, also known colloquially as Tekong, is the largest of Singapore's outlying islands, with an area of 24.43 km2. The island is still expanding due to land reclamation works on its southern and northwestern coasts which will eventually subsume many of its surrounding small islets, including Pulau Tekong Kechil. Pulau Tekong is found off Singapore's northeastern coast, east of Pulau Ubin. Geographically, it is nearer to Johor, Malaysia than the Singapore main island itself. The Pulau Tekong Reservoir is also on the island.
