Wife Swap is a British reality television programme that aired on Channel 4 from 7 January 2003 to 15 June 2017.

In the programme, two families, usually from different social classes and lifestyles, swap wives/mothers – and sometimes husbands – for two weeks. In fact, the programme will usually deliberately swap wives with dramatically different lifestyles, such as a messy wife swapping with a fastidiously neat one. Despite using a phrase from the swinging lifestyle, couples participating in the show do not share a bed with the "swapped" spouse while "swapping" homes.

In November 2009, Channel 4 announced that they had cancelled Wife Swap, and no new episodes of the show would be made for the channel. The final episode was broadcast in December 2009.

It was announced that Wife Swap would return for a special Brexit episode to air on 15 June 2017 on Channel 4.
