Hormuz, also spelled Hormus or Hormoz, refers primarily to an Iranian island in the Persian Gulf, located just 5 miles (8 km) off the coast and 18 kilometers east of Qeshm Island. This largely barren, hilly landmass lends its name to the adjacent Strait of Hormuz, a narrow waterway connecting the Persian Gulf to the Gulf of Oman.
The name itself carries deep historical roots, appearing in various forms throughout different eras. The older appellation 'Ormuz' is frequently encountered in historical texts, reflecting the long-standing Persian origin (Hormoz, هرمز). These variations highlight the name's persistence and evolution across diverse linguistic and cartographic traditions.
