Larak Island is a small, strategically vital Iranian island located in the Strait of Hormuz, part of the Hormozgan province. It is a geographical feature that serves as a key military and geopolitical asset for Iran.
The island's strategic significance dates back to the 16th century, when it was under the dominion of the Portuguese, who built a fort there to guard freshwater supplies and control traffic in the Persian Gulf. It was returned to Iranian sovereignty during the reign of Shah Abbas. Its modern geopolitical role began in the 1980s; it became a major oil export point along with Kharg Island in 1987, though its oil transfer site was destroyed by Iraqi forces in May 1987.
Larak Island's mechanism is its location at the narrowest point of the Strait of Hormuz, which is only 24 miles (39 km) from Oman's Great Quoin Island. It functions as a critical node in Iran's "arch defence" system, housing an Islamic Revolutionary Guard Corps Navy (IRGCN) base and equipped with radar and electronic monitoring to track maritime traffic. Missile units on the island are positioned to target ships passing through the strait.
The island connects directly to the concept of the Strait of Hormuz chokepoint, which is crucial for global oil supplies. It is often mentioned alongside nearby Qeshm Island and Hormuz Island as part of Iran's territorial network for surveillance and control. Recently, the island has been described by analysts as Tehran's "toll booth," with Iran reportedly forcing ships to pay fees for safe passage. This mechanism was highlighted in March 2026, when two ultra-large container ships were tracked making a U-turn near the island.
