The Miguel Malvar class is a class of patrol corvettes in the Philippine Navy, and is considered to be its oldest class of corvettes. Formerly used by the US Navy as Admirable-class minesweepers.

In the Philippine Navy, the vessels after undergoing upgrades and modifications were re-categorized as corvettes.

One ship, the former USN USS Quest (AM-281) was supposedly a member of this class but was converted into a non-combatant Presidential Yacht by the Philippine Navy in 1948 as the RPS Pag-asa (APO-21) which was later renamed as RPS Santa Maria, and as RPS/BRP Mount Samat.
