Sanur is one of the municipalities of Jenin governorate, in its south-eastern part, at about 550 m above sea level.
It grew around a towering hilltop fortress whose walls still stand. In the late Ottoman era Sanur was a fortified village of the Jarrar family that limited the authority of the Ottoman governors and of the Tuqan family of Nablus.
The town overlooks the 15,000-dunam Sanur plain, the third largest in Palestine. Its population was 4,067 in 2007 and 5,036 in 2017.
