Quest Red is a British free-to-air television channel in the United Kingdom broadcasting factual, lifestyle, crime and reality programming aimed at a female audience.

In mid-February 2017, shortly after the completion of an eleventh-hour carriage deal with Sky to retain a presence on the satellite platform for its current and future channels, Discovery Communications head David Zaslav told a corporate conference call that a second Freeview channel, to sit alongside Quest, would launch during 2017.

As part of Sky's major EPG reshuffle on 1 May 2018, Quest Red (and +1) became available to both Ireland and Northern Ireland customers, in addition to moving to 149 for Great Britain customers, a slot they acquired from ITV Digital Channels, who previously had ITVBe on that slot apart from regions where STV is on channel 103.

On 8 January 2024, Quest Red started broadcasting US crime dramas from Warner Bros. Television.

A placeholder for Quest Red was made available on the Virgin Media platform early in the morning of 15 March, ahead of the channel's launch; the new channel was added to the Sky programme guide at approximately 10:45 am on launch day in Great Britain only, and to Freeview from noon.
