The Henares (Spanish: [eˈnaɾes] ^ⓘ) is a river in Spain, tributary of the Jarama. It has its source in the Sierra Ministra, in the village of Horna, near Sigüenza, in the province of Guadalajara. Its tributaries are the Torote, the Sorbe, the Cañamares, the Salado, the Dulce, the Aliendre, and the Bornova.

Henares in Spanish is the plural of henar 'hayfield' (derived from the Latin word faenum 'hay'), because formerly there were hay fields on the river's banks.
