Gilbert Italia Gapay is a retired Philippine Army general who served as the 54th Chief of Staff of the Armed Forces of the Philippines. Prior to his appointment, he served as the 61st Chief of the Army and the commander of the Armor "Pambato" Division.

The Chief of Staff of the Armed Forces of the Philippines (CSAFP) is the highest-ranking military officer and the head of the Armed Forces of the Philippines (AFP), including all service branches under its command. The position is usually held by a four-star rank of General or Admiral. Its direct equivalent in the US Armed Forces is the Chairman of the Joint Chiefs of Staff. Unlike its US counterpart, which is merely supervisory, the Chief of Staff has complete operational control within the military hierarchy and is responsible for the overall operations of the AFP.
