Radial Road 1, more commonly referred to as R-1, is a 41.5-kilometre (25.8 mi) long network of roads and bridges that altogether form the first arterial road of Manila in the Philippines. The road runs north-south linking the City of Manila to the Metro Manila cities of Pasay, Parañaque and Las Piñas, down to Bacoor, Imus, Kawit, Noveleta, General Trias, Tanza and Naic in the province of Cavite.

The road consists of the following segments from north to south:

Between its northern terminus at Roxas Bridge (formerly Del Pan Bridge) and Padre Burgos Avenue, R-1 is known as Bonifacio Drive. It serves the districts of Intramuros and Port Area and meets Roxas Boulevard in Rizal Park.

R-1 becomes Roxas Boulevard after intersecting with Padre Burgos Avenue. This section of R-1 in Rizal Park is marked as Kilometer 0. It is a waterfront promenade which leads out of Ermita and Malate in the City of Manila into Pasay and Parañaque. Roxas Boulevard ends at the junction with NAIA Road.

Between NAIA Road and Antero Soriano Highway in Kawit, Cavite, R-1 is known as the Manila–Cavite Expressway (also known as Coastal Road or CAVITEx). This tollroad connects Parañaque with Las Piñas and leaves Metro Manila for Bacoor and Kawit in the province of Cavite.
