Torrijos is one of six (6) municipalities comprising the province of Marinduque in the Mimaropa Region. The town is politically subdivided into twenty-five (25) barangays, and is a part of the Lone Congressional District of Marinduque.

Torrijos is known as the site of the Battle of Pulang Lupa, an engagement on September 13, 1900 during the Philippine-American War, which pitted the forces of Colonel Maximo Abad and American Captain Devereux Shields, in which Abad’s men annihilated the American troops. It was one of the worst defeats suffered by the Americans during the war.

A monument with a mural of the historic battle now stands on the mountain where the battle took place, known as Pulang Lupa (Red Mountain) due to the red soil, also said to represent the bloodshed during and after the Philippine-American War.
