Unaizah (Arabic: عنيزة ʿUnaizah) or officially The Governorate of Unaizah (also spelled Onaizah, Onizah, or Unayzah; Arabic: محافظة عنيزة Muḥāfiẓat ʿUnaizah) 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 184,600 (2022 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.

Unaizah is in the south of Al-Qassim Province and at the heart of the historical region of Najd. It is located roughly 30 kilometers from Buraydah (the capital of the province) and more than 300 kilometers north of the Saudi capital, Riyadh. Unaizah lies in the northern-central region of the Najd and to the south of the Wadi al-Rummah (Rumma Valley), which is the longest valley on the Arabian Peninsula. It is surrounded by sand dunes to its north and west, which are known locally as the Al-Ghamis Sands. The Al-Ghadha Woods are located to the north of the city. Next to Unaizah is the Al-Aushaziyah salt lake (or Sabkha), which is considered an official part of the city.

Unaizah has a hot desert climate (Köppen Climate Classification BWh), with long, extremely hot summers and short, very mild winters. The average high temperature in August is 43.6 °C (110.5 °F). The city experiences very little precipitation, especially in summer, but receives a fair amount of rain in March and April. It is also known to have dust storms during which the dust can be so thick that visibility is under 10 m (33 ft).

Unaizah is an agricultural area and produces wheat and barley of various strains. The region also grows grapes, grapefruits, lemons, leeks, mandarins, oranges, pomegranates and dates.

Leeks (kurrat) are a very important part of the local culture of Unaizah. They are popular among the locals and comprise a significant portion of the local agricultural industry.

An annual Date Season Festival has been held in September since the early 2000s, giving Unaizah the distinction of hosting the second largest date festival in the Persian Gulf and the Middle East. The festival rivals the date festival of neighboring Buraydah's, which is sometimes known as "Buraydah, the City of Dates".

Unaizah's 2008 (4th) annual Date Festival was known as the "Unaizah International Date Festival", though the city's title "Unaizah, the Kingdom of Dates" was retained as a motto. Many people from different places of the Middle East come to see this festival and buy dates because they know there is a good quality of dates.

The Unaizah Municipality (Arabic: بلدية عنيزة or baladiyah Arabic: البلدية ) was founded in AH 1381 (1961/1962) in Unaizah. It carries out the civic administration for the Metropolitan area of Unaizah. The municipality was established for the purpose of maintaining villages, regulating construction projects and systematizing public health, safety measures and the construction of the infrastructure of the city such as roads, the stormwater drainage network and street lighting. The Unaizah Municipality has 3 main agencies:

• Services Agency : Responsible of maintenance and operation of facilities in the city.
• Project Management Agency: Responsible of managing and regulating the construction projects in the city.

Unaizah is home to some pioneers in education; the first Saudi person from Al-Qassim Province to earn a PhD. degree was from Unaizah, and his name was Abdulaziz Al-Khowaiter. The first Saudi female from Al Qassim Province to earn a PhD degree was also raised in this city. Her name was Ebtisam Al Bassam.

One of the first cities to embrace female education in Al-Qassim Province and Najd was Unaizah. It faced resistance from neighboring provinces and brought Unaizah at the forefront of a national debate. After lengthy negotiations, the capital city of Qassim, Buraidah a sister city of Unaizah, officially recognized the right of an education for females, partly due to King Abdulaziz's interference in settling the dispute.

Today, there are many public schools in Unaizah for all three educational levels (primary, intermediate, and secondary). There are also two private schools and one private international school. There is also a boys' technological secondary school in the city and a technological college, as well as a girls' educational college.
