Outnumbered is a British sitcom about the Brockman family, starring Hugh Dennis as the father, Claire Skinner as the mother and their three children played by Tyger Drew-Honey, Daniel Roche and Ramona Marquez.

There were five series, which aired on BBC One from 2007 to 2014. A one-off Christmas reunion special aired on 26 December 2016. The following year, Hugh Dennis expressed hope that more one-off specials would be made following the success of the 2016 Christmas special. A further Christmas special was broadcast on BBC One on 26 December 2024.

Produced by Hat Trick Productions, Outnumbered was written, directed and produced by Andy Hamilton and Guy Jenkin, although parts of the show are semi-improvised. The adult actors learn the scripts, while the children are given last-minute instructions by the writers instead.

The programme has received critical acclaim for its semi-improvisational scripting and realistic portrayal of children and family life. Ratings have been average for its time slot, but the series has won a number of awards from the Comedy.co.uk awards, the Royal Television Society, the British Comedy Awards and the Broadcasting Press Guild. Plans for an American adaptation were announced in February 2009, but as of November 2024 this has not materialised. The original series began airing in the US on BBC America on 30 July 2011, as well as airing on PBS stations.
