The Johore Strait (also known as the Tebrau Strait, Straits of Johor, Selat Johor, Selat Tebrau, and Tebrau Reach) is an international strait in Southeast Asia, between Singapore and Peninsular Malaysia.

The strait separates the Malaysian state of Johor on the mainland Malay Peninsula to the north, from Singapore and its islands on the south. It connects to the Strait of Malacca on the west, and the Singapore Strait on the southeast.

The mouth and delta of the Johor River is on its northeast side in Malaysia.

There are currently two bridges crossing the strait. The Johor–Singapore Causeway, known simply as "The Causeway", links Johor Bahru and Woodlands in Singapore. The Malaysia–Singapore Second Link bridge is further west over the strait, links Iskandar Puteri in Malaysia and Tuas in Singapore.

In 2003, Malaysia wanted to build a bridge across the strait to replace the existing causeway, but negotiations with Singapore were not successful. The main reasons cited for the change were:

In August 2003, Malaysia announced that it was going ahead with a plan to build a gently sloping, curved bridge that would join up with Singapore's half of the existing causeway. The plans included a swing bridge for the railway line. However, plans to build the bridge have been called off as of 2006.

Major tributaries which empty into the Strait of Johore include:

In the Malay language, Sungai is the word for river.

Pollution along the Johore Strait is notable.

The area is also a source of environmental contention between Malaysia and Singapore, due to land reclamation projects on both sides of the Causeway. There have been suggestions that the ongoing land reclamation projects may impact the maritime boundary, shipping lanes, and water ecology of the Malaysian side. Environmental Impact Assessments are requested before any reclamation is carried out such as the Forest City project.
