Bolarque Dam (Spanish: Presa de Bolarque) is a concrete gravity dam on the Tagus in Spain, where the river forms the border between the provinces of Cuenca and Guadalajara.

About 6 km downstream from the dam is the José Cabrera Nuclear Power Station.

The dam was officially inaugurated on June 23, 1910 by king Alfonso XIII.

Bolarque II is the starting point of the Tagus-Segura Water Transfer.
