Sinnar (Pronunciation: [sinːəɾ]) is a city and a municipal council in Sinnar taluka of Nashik district in the Indian state of Maharashtra. Sinnar is the third largest city in Nashik district after Nashik and Malegaon.

Traditionally, it is believed that Sinnar was founded by Rav Singuni, a Gavli chieftain.^[1] His son Rav Govinda built the great temple of Gondeshwara at a cost of 2 lakh rupees.^[2]

At its peak, the Seuna or Yadava dynasty (850 - 1334) ruled a kingdom stretching from the Tungabhadra to the Narmada Rivers, including present-day Maharashtra, north Karnataka and parts of Madhya Pradesh. The capital was at Devagiri, now known as Daulatabad in Maharashtra. The reign of the Yadava dynasty declined after the conquest of the Daulatabad Fort by Alauddin Khalji in 1294. Khilji used tactics which were unthinkable to the evolved, cultured minds of those times such as raping women, mass killing of surrendered soldiers, breaking of temples, kidnapping, ravaging innocent villages, poisoning wells and rivers and breaking all treaties as per convenience. Further conquest by Malik Kafur, Alauddin's general, in 1312 resulted in the killing of the members of the Yadava clan ending this illustrious dynasty. It is also the birthplace of Baji Rao I,the mighty general of Maratha Empire.

Sinnar is located at 19°51′N 74°00′E / 19.85°N 74.0°E / 19.85; 74.0.^[3] It has an average elevation of 651.4 metres (2135 feet).
