A Voz do Brasil is a state-run radio news program, produced by Empresa Brasil de Comunicação, with mandatory broadcasting (except in exceptional cases where the Executive Branch exempts it) whose transmission must occur from Monday to Friday (except holidays) on all Brazilian radio stations, in the time slot from 7:00 PM to 10:00 PM, with a duration of 1 hour. If the transmission is not at 7:00 PM, the station is required to inform at this time what time A Voz do Brasil will be transmitted.

It is the oldest radio program in the country and the southern hemisphere still in broadcasting.
It was created in 1935, during the government of Getúlio Vargas, under the name Programa Nacional.
In 1938, it became mandatory broadcasting with a fixed schedule from 7:00 to 8:00 PM, and its name changed to A Hora do Brasil. In 1971, it adopted the name A Voz do Brasil, which it maintains to this day.
