Nashaq (Minaean: 𐩬𐩦𐩤 romanized: Nšq; modern day Kharbat Al-Bayda', Arabic: خربة البيضاء) is the name of an ancient South Arabian city in the northern al-Jawf region of present-day Yemen, in the territory of the ancient Kingdom of Ma'in.

Karib'il Watar (around 685 BC) launched a campaign to capture Nashan and Nashaq which lasted for three years.

In 25 BC, Nashaq was mentioned as "Nescus"[note 1] during Aelius Gallus's expedition to Arabia Felix under orders of Augustus against Saba'.

However, the expedition ended in critical failure and the Romans accused a Nabataean guide called "Syllaeus" of misleading them.

This expedition was mentioned by Greek geographer Strabo in which he named Ilasaros as the ruler of Hadhramaut at that time.
