Doulos Broadcasting Network (also known as DBN) is a Tongan Christian television station, affiliated with the US-based Trinity Broadcasting Network. As of 2011, the station was located close to the TBC facility in Nukuʻalofa which combined a church and a television production facility. It received a satellite feed of the main TBN network from the NSS-9 satellite and was equipped with a Teko transmitting tower. Unlike Television Tonga, which broadcast on VHF, DBN broadcast on UHF.

DBS was reported to only cover the islands of the Tongatapu Group, in southern Tonga, where most of the population lives. 70% of its programming was sourced from the TBN relay; the remaining 30% was local programming.

The station was commissioned on 2 May 2001 and started broadcasting weeks later.Third TV station, Matangi Tonga, 30 June 2001, retrieved 31 July 2026 Its founder was Reverend Isileli Taukolo.
