Gogglebox is a British reality television series created by Stephen Lambert, Tania Alexander and Tim Harcourt, and broadcast on Channel 4.

The first series launched on 7 March 2013, and the twenty-fourth series began airing on 13 September 2024. The show was narrated by Caroline Aherne from its launch until April 2016, shortly before her death, after which Craig Cash took over.

The show has won numerous awards. In 2014 and 2022, it won a BAFTA in the Reality & Constructed Factual category. From 2015 to 2018, in 2021, 2022 and 2023, it won a National Television Award. The success of Gogglebox spawned three spin-off series, including a version featuring children (Gogglesprogs), a version featuring 16- to 24-year-olds as they watch online content (Vlogglebox) and a version featuring celebrities (Celebrity Gogglebox).
