Larak Island (also Lark Island) is a small Iranian island located off the coast of Bandar Abbas, Iran, east of Qeshm Island and south of Hormuz Island. The narrowest part of the Strait of Hormuz () lies between this Iranian island and Oman's Great Quoin Island.
The island has been one of Iran's major oil export points since 1987.
During their occupation in the 16th century, the Portuguese built fortresses here, as well as on the nearby Qeshm and Hormuz Islands. The island contains an Iranian military base which maintains several Chinese-made Silkworm HY-2 surface-to-surface missiles placed there in 1987.
A floating terminal was established on Larak Island in June 1986. The island was bombed by Iraq in November and December 1986, as part of the IranâÂÂIraq War. As part of Operation Praying Mantis, the Iranian frigate Sahand was sunk by the United States Navy, 200 meters southwest of Larak Island. On 14 May 1988, the largest ship at the time, the Liberian supertanker, Seawise Giant, whilst carrying crude Iranian oil, was sunk by Iraqi anti-ship missiles off the coast of Larak Island. The ship was later refloated, repaired and used for another few years.
In late March during the 2026 Iran war Iran began routing oil tankers north of Larak Island for a fee ("Tehran's Tollbooth"); distinct from the main channel, this route affords visual inspection of the ships by the IRGC Navy and port authorities.
Larak Island is located in the Larak Rural District, which is within the Central District of Qeshm County. Two settlements are on the island: Larak Shahri and Larak Kuhi. Larak Shahri is the largest of the two villages, with a population of 466 people and 98 families.
The waters around Larak Island are one of the most diverse coral reef areas in the environment of the Persian Gulf. There are 37 species of scleractinian corals identified around Larak Island.
