Etymology

The strait of Hormuz may have been named after the mother of King Shapur II, King of Persia, who ruled between 309 and 379 CE.

Her name was Ifera Hurmiz.

The opening to the Persian Gulf was described, but not given a name, in the Periplus of the Erythraean Sea, a 1st-century mariner's guide:

At the upper end of these Calaei islands is a range of mountains called Calon, and there follows not far beyond, the mouth of the Persian Gulf, where there is much diving for the pearl-mussel. To the left of the straits are great mountains called Asabon and to the right there rises in full view another round and high mountain called Semiramis; between them the passage across the strait is about six hundred stadia; beyond which that very great and broad sea, the Persian Gulf, reaches far into the interior. At the upper end of this gulf there is a market-town designated by law called Apologus, situated near Charaex Spasini and the River Euphrates.

In the 10th – 17th centuries AD, the Kingdom of Ormus, which seems to have given the strait its name, was located here. Scholars, historians and linguists derive the name "Ormuz" from the local Persian word هورمغ Hur- mogh meaning date palm. In the local dialects of Hurmoz and Minab this strait is still called Hurmogh and has the aforementioned meaning. The resemblance of this word to the name of the Zoroastrian god هرمز Hormoz (a variant of Ahura Mazda) has resulted in the popular belief that these words are related.

Jodocus Hondius labels the Strait Basora fretum ("Strait of Basra ") on his 1606 map of the Ottoman Empire.
