24 Hours in Police Custody is a British television documentary series shown on Channel 4. It primarily follows Bedfordshire Police as they investigate cases in Luton. The programme is made by The Garden; the same production company that makes 24 Hours in A&E.

The first series of seven episodes aired in late 2014. Filming took place at Luton Police Station over a six-week period using more than 80 cameras. Channel 4 commissioned further series, with the second airing in early 2015. A few episodes have taken place wholly or partly elsewhere in Bedfordshire and in Cambridgeshire. Series 10 began broadcasting on 22 March 2021.
