Religion is a fundamental part of Brazilian culture and governs and informs the lives of a large swathe of the population, this is especially true within rio de janeiro, where the carioca culture places much emphasisi and importance on religious activities, festivals, and events.

As a result, a number of religious radio stations providing biblical reading, sermons and gospel music to cater to the spiritual interests of the cariocas.

For evangelical gospel music, discussions and sermons rádio 93 FM, and Feliz FM, at 89.5 FM are common options - For Catholic sermons, discussions and news a common option is Rádio Catedral, at 106.7 FM, while for slightly lighter Catholic coverage, including music and entertainment Rádio Aliança, at 98.7 FM, is also available.
