Nayar River is a perennial, non-glacial river in the North Indian state of Uttarakhand. The river system is one of the largest non-glacial perennial rivers in the state, second only to Ramganga (West) and flows entirely in the district of Pauri Garhwal. The two main branches of the river, Nayar East and Nayar West along with Ramganga river, rise in the dense forests and high meadows of Dudhatoli and merge to form Nayar roughly one kilometre ahead of Satpuli. Satpuli is a town on the left bank of Nayar East river.
