Bandar Abbas is a port city and capital of Hormozgān Province on the southern coast of Iran (Persia), on the Persian Gulf. The city occupies a strategic position on the narrow Straits of Hormuz, and it is the location of the main base of the Iranian Navy. It had an estimated population of 352,173 in 2005.
Bandar Abbas has always been a port, and as such its various names have all addressed this function. The most common name over time (Gameroon) has traditionally been said to derive from Persian gümrük, customhouse (from Late Greek kommerkion, from Latin commercium, "commerce"), but is now speculated to be from Persian kamrūn, shrimp (which in Portuguese is camarão, similar to the former Portuguese name).
Bandar Abbas is situated on flat ground with an average altitude of 9 m (30 ft) above sea level. The nearest elevated areas are Mt. Geno, 17 km (11 mi) to the north, and Mt. Pooladi, 16 km (10 mi) to the northwest of the city. The closest river to Bandar Abbas is the River Shoor, which is rooted from Mt. Geno and pours into the Persian Gulf, 10 km (6 mi) east of the city.
