Antonio Abad y Mercado (May 10, 1894 – April 20, 1970) was a prominent Filipino poet, fictionist, playwright and essayist.

Antonio Abad y Mercado was born in Barili, Cebu, under the Captaincy General of the Philippines, on 10 May 1894.

He was a strong advocate of the Spanish language and Hispanic-Filipino culture when it was discouraged during the American colonial period in the Philippines.

Abad was one of the leading contributors of Hispanic-Filipino literature during his time, producing novels and plays criticizing the occupation of the islands by the Americans.

One of his last works, a multilingual dictionary of Spanish, English, Cebuano, Ilocano and Kapampangan, remained unfinished after his death on 20 April 1970.
