Sennar (Arabic: سنار Sannār) is one of the 18 wilayat or states of Sudan.

The main economic activity is agriculture, with the irrigated scheme of Suki, the sugar factory of Sennar, and a number of fruit growers (including bananas and mangoes) located on the banks of the Blue Nile.

It took control of other cities such as Dinder, Mazmoum, and El-Suki and nearby areas connecting it while launching an incursion into Blue Nile state.

However in October, the Sudanese military attacked and took control of Jebel Moya.

As of 2025, the RSF remains sieged in southwest Sennar in control of the village of Mazmoum.
