Nizwa (Arabic: نزوى‎) is the largest city in the Ad Dakhiliyah Region in Oman and was the capital of Oman proper. Nizwa is about 140 km (1.5 hours) from Muscat. The population is estimated at around 70,000 people including the two areas of Burkat Al Mooz and Al Jabel Al Akhdar.

Nizwa is one of the oldest cities in Oman and it was once a center of trade, religion, education and art. Its Jama (grand mosque) was formerly a center for Islamic learning. Nizwa acquired its importance because it has been an important meeting point at the base of the Western Hajar Mountains. Set amid a verdant spread of date palms, it is strategically located at the crossroads of routes linking the interior with Muscat and the lower reaches of Dhofar thus serving as the link for a large part of the country. Today, Nizwa is a diverse prosperous place with numerous agricultural, historical and recreational aspects. Nizwa is a center for date growing and is the market place for the area.
