Tiran Island is an island within the maritime borders of Saudi Arabia that was administered by Egypt in the past. However, sovereignty of the two Red Sea islands, Tiran and Sanafir, was ceded officially to Saudi Arabia as part of a maritime borders agreement between Egypt and Saudi Arabia. The agreement subsequently was approved by the Egyptian Parliament and finally ratified by the Egyptian President on 24 June 2017.

The island is located at the entrance of the Straits of Tiran, which connects the Red Sea to the Gulf of Aqaba. It has an area of about 80 square kilometres (31 square miles). It is part of the Ras Muhammad National Park. The Straits of Tiran is Israel's only access from the Gulf of Aqaba to the Red Sea, and Egypt's blockade of the Straits of Tiran on 22 May 1967 was the casus belli for Israel in the Six-Day War.

Tiran Island is of strategic significance in the area, as it forms the narrowest section of the Straits of Tiran, which is an important sea passage to the major ports of Aqaba in Jordan and Eilat in Israel.
