Right to Reply (sometimes called R2R) is a British television series shown on Channel 4 from 1982 until 2001, which allowed viewers to voice their complaints or concerns about TV programmes.

A notable feature of Right to Reply was the "video box", which gave viewers a third means of communicating with the programme in the 1980s, alongside letter or telephone.

In the late 1990s (until 2001) the "Right to Reply 500", a group of 500 TV viewers, answered weekly online surveys about current television issues.

Channel 4's 2001 decision to end Right to Reply, after a run of more than 18 years, was criticised by its fans, since nothing similar remains in its place.
