Unaizah or officially The Governorate of Unaizah, is a Saudi Arabian city in the Al Qassim Province. It lies south of the province capital Buraydah and north of Riyadh, the capital of the Kingdom of Saudi Arabia. It is the second largest city in Al-Qassim Province with a population of 163,729 (2010 census).
Historically, Unaizah was an important stopping point for Muslim pilgrims coming from Mesopotamia (now Iraq) and Persia (now Iran) on their way to Makkah. Many scientists and historians believe that Unaizah was inhabited hundreds of years before the spread of Islam, citing its reference in numerous poems from some of the most important poets of pre-Islamic Arabia such as Imru Al-Qais
