The street marks the original shoreline of Manila Bay as it existed during the Spanish colonial period.
It was then known as Calle Real (Spanish for "royal street") which served as the national road that linked Manila with the southern provinces.

The old coastal highway ran from Ermita to Muntinlupa passing through Pasay (where it is now known as Harrison Avenue), Parañaque (now known as Elpidio Quirino Avenue), and Las Piñas (now known as Diego Cera Avenue and Alabang–Zapote Road).

The current shoreline is about 180 meters west on Roxas Boulevard (formerly Dewey Boulevard) which was reclaimed in the early 1900s during the American colonial period.
As with most other streets in Manila, it was renamed in 1921 after a Filipino writer and patriot, Marcelo Hilario del Pilar.
