DZRB (738 AM) Radyo Pilipinas 1 (RP1) is an AM station owned and operated by Philippine Broadcasting Service in the Philippines. The station's studios are located in 4/F, PIA/Media Center Building, Visayas Avenue, Brgy. Vasra, Diliman, Quezon City, and its transmitter is located at Brgy Marulas, Valenzuela City. DZRB is the first radio station in the Philippines before the launch of DZRH. DZRB operates 20 hours daily (except during Maundy Thursday to Black Saturday annually) from 4 am to 12 mn.

On June 5, 2017, the former Radyo ng Bayan was rebranded as Radyo Pilipinas 1 (RP1).

On May 8, 1933, the United States-sponsored Insular Government established and operated radio station KZSO in the Philippines on the frequency of 710 kilohertz with a power of 10,000 watts through the United States Information Service. In 1944, the callsign was change to KZFM, named after Frederick Marquardt.

In September 1946, two months after the Philippines became an independent country from the U.S.A., KZFM was turned over to the Philippine government. With the transfer was born the Philippine Broadcasting Service, PBS the second broadcasting organization after Manila Broadcasting Company.

The station was first operated by the Department of Foreign Affairs until it was transferred to the Radio Broadcasting Board (RBB) which was created by President Manuel Quezon on September 3, 1937. Meanwhile, in the same year, an international telecommunications conference in Atlantic City, New Jersey, reassigned the letter "D" to replace the former "K" as the initial call letter for all radio stations in the Philippines. In January 1942, the RBB was abolished to give way to the establishment of the Philippine Information Council (PIC) which then assumed the function of the RBB, including the operation of DZFM. In turn, the PIC was abolished on July 1, 1952, and since then, until the creation of the Department of Public Information (DPI) in 1959, DZFM and the Philippine Broadcasting Service (PBS) had been operated under the Office of the President.
