The Singapore Strait is a 105-kilometre-long (65 mi), 16-kilometre-wide (9.9 mi) strait between the Strait of Malacca in the west and the Karimata Strait in the east.
Singapore is on the north of the channel, and the Riau Islands are on the south.
The Indonesia-Singapore border lies along the length of the strait.

It includes Keppel Harbour and many small islands.
The strait provides the deepwater passage to the Port of Singapore, which makes it very busy.
Approximately 2,000 merchant ships traverse the waters on a daily basis.
The depth of the Singapore Strait limits the maximum draft of vessels going through the Straits of Malacca, and the Malaccamax ship class.
