Mark Anthony Gayoso Santos (born June 14, 1963) is a Filipino politician who is the representative for Las Piñas's at-large district, serving since 2025. Before being elected to Congress, he had served as a member of Las Piñas's city council from 2022 to 2025 and previously from 2010 to 2019.

As a councilor, Santos was a vocal critic of the dominant Villar family in local congressional politics. In the 2025 Philippine House of Representatives election, he defeated Senator Cynthia Villar in a result described by several media outlets as a major electoral upset.
