Diego Cera Avenue

Padre Diego Cera Avenue, or simply Diego Cera Avenue, is a major north-south collector road in Las Piñas, Metro Manila, Philippines. It is a four-lane undivided arterial running parallel to the Manila–Cavite Expressway to the west from Manuyo Uno at Las Piñas' border with Parañaque in the north to Zapote near the border with Bacoor in the south. It is a continuation of Elpidio Quirino Avenue from Parañaque and was originally a segment of Calle Real in Las Piñas. The road is a component of the National Route 62 (N62) of the Philippine highway network and  Radial Road 2 (R-2) of Manila's arterial road network.

The avenue marks the original shoreline of Manila Bay in Las Piñas as it existed during the Spanish colonial period. Prior to the construction of the Coastal Road in 1985, the road served as the highway linking Manila with Cavite and other southern provinces. The Manila Bay shoreline is currently about 400 to 600 m to the west.

The road is situated in the Las Piñas historical corridor being home to the city's oldest structures such as the Las Piñas Church, the Las Piñas Gabaldon Hall, and the old Las Piñas District Hospital. It was named for Fray Diego Cera de la Virgen del Carmen (1762–1832), the Spanish missionary from Huesca who designed and built the Bamboo Organ in 1824.
