Serra de Cavalls is a mountain chain located at the southern end of the Catalan Pre-Coastal Range, Catalonia, Spain.

This mountain range lies within the Benissanet, Gandesa and El Pinell de Brai municipal term.

These mountains, along with Serra de Pàndols further south and Serra de la Fatarella in the north, were the scenario of bloody battles during the Battle of the Ebro in the Spanish Civil War (1936 - 39).

In nearby Serra de Pàndols stands a monument to those who died in the battles on Hill 705.

[3] There is also opposition to the attempt to locate a vast rubbish dump in an area that is very close to these mountains.
