Its early name, Ayombong, changed to Dumalag in 1631. The name has several possible origins, including the word dalag for yellow, the river’s color, the term dumalaga for young chicken, or a response to Spanish visitors describing the river as gadalag. A family name may also be linked to it.

Dumalag was founded by the Augustinians in 1590 and returned to their care in 1614 after a brief shift to the bishopric. The town’s first church and convent were built between 1600 and 1720, and the present church began in 1833. Much of it was damaged in the 1948 earthquake and later rebuilt.
