San Fernando, town, west-central Luzon, Philippines. Located on a bay of the South China Sea formed by a peninsula that ends in San Fernando Point, it served a tobacco- and rice-growing region as the northern terminus of the Philippine National Railway until the line was extended to Bacnotan in 1955. The town is on Luzon’s main western coastal highway. Its outport, Poro, is the only national port of entry in northern Luzon; imported goods are received, and the region’s commercially bundled tobacco leaves are exported. The city has a modern cathedral (1976) and a Chinese pagoda; nearby to the south are the ruins of a church built in 1674. Pop. (2000) 102,082; (2010) 114,963.
