The Sussex Police and Crime Commissioner is the police and crime commissioner, an elected official tasked with setting out the way crime is tackled by Sussex Police in the English County of Sussex. The post was created on 21 November 2012, following an election held on 15 November 2012, and replaced the Sussex Police Authority. The current commissioner is Conservative Party politician Katy Bourne, who was re-elected in May 2016. The police and crime commissioner is required to produce a strategic Sussex Police and Crime Plan, setting out the priorities for Sussex Police, and their work is scrutinised by the Sussex Police and Crime Panel.

The post was the first to be elected on a Sussex-wide basis since 1832 when the Sussex parliamentary constituency was replaced by constituencies for Sussex's eastern and western divisions.

The Sussex Police and Crime Commissioner is elected by the first past the post method for a fixed term of four years, although the inaugural term of the post was for three and a half years, and the 2016-2021 term was five years, owing to the 2020 election being delayed a year by the coronavirus pandemic.^[1] Elections to the post previously used the supplementary vote method, but this was changed in May of 2023.^[2]
