TV Rio Sul (channel 13) is a TV Globo-affiliated television station based in Resende, a city in the state of Rio de Janeiro. The station covers the southern and central-south regions of Rio de Janeiro (with the exception of the municipality of Areal which, since 1997, has received the signal from InterTV Serra+Mar).

The weekly program (renamed in 2017) premiered in 1997. TV Rio Sul opened a new regional unit in Angra dos Reis in 2000. In 2001, its website Rio Sul Net openet, being shut down in April 2013 due to the realignment of Globo's affiliate websites. In 2009, a fourth unit, geographically distant from the Resende offices and the adjacent regional units, opened in Três Rios.
