Ma'in was an ancient South Arabian kingdom in modern-day Yemen. It was located along the strip of desert called Ṣayhad by medieval Arab geographers, which is now known as Ramlat al-Sab'atayn. Wadd was the national god of Ma'in. The spoken language was Minaic. The kingdom appears in the historical record in the 8th century BCE, and transition from a city-state to kingdom in the last quarter of the 7th century BCE. The date of the end of Ma'in is heavily disputed, but the most popular hypothesis places its demise in the 1st century CE.
