Bandar-Abbas (Persian: بندرعباس‎) or Bandar-e ‘Abbās (Persian: بندر عباس), also Romanized as Bandar ‘Abbās, Bandar ‘Abbāsī, and Bandar-e ‘Abbās; formerly known as Cambarão and Port Comorão to Portuguese traders, as Gombroon to English traders and as Gamrun or Gumrun to Dutch merchants) is a port city and capital of Hormozgān Province on the southern coast of Iran, 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. Bandar Abbas is the capital and also largest city of the province Hormozgān. At the 2006 census, its population was 367,508, in 89,404 families.

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).
