2017 Greater Manchester mayoral election

The inaugural Greater Manchester mayoral election was held on 4 May 2017 to elect the Mayor of Greater Manchester. The next successive election was due to be held on 7 May 2020, but due to that year's outbreak of the novel Coronavirus, the election was postponed until May 2021. Subsequent elections are legislatively required to be held every four years thereafter. The electoral system used for the election is the supplementary vote (SV).

The mayor leads the Greater Manchester Combined Authority, sitting alongside the leaders of the ten metropolitan borough councils who form the mayor's cabinet. The creation of the position was part of a devolution deal giving local government additional powers and funding, enacted via the Cities and Local Government Devolution Act 2016. The interim mayor was Tony Lloyd, the Greater Manchester Police and Crime Commissioner. The office of police and crime commissioner was subsumed into the mayor's role.

Nominations for candidates wishing to stand in the election closed on 4 April 2017, after which the final list of candidates was published.

Electoral system
The election used the supplementary vote system, in which voters express a first and a second preference of candidates.
 * If a candidate receives over 50% of the first preference vote the candidate wins.
 * If no candidate receives an overall majority, i.e., over 50% of first preference votes, the top two candidates proceed to a second round and all other candidates are eliminated.
 * The first preference votes for the remaining two candidates stand in the final count.
 * Voters' ballots whose first and second preference candidates are eliminated are discarded.
 * Voters whose first preference candidates have been eliminated and whose second preference candidate is in the top two have their second preference votes added to the count.

All registered electors (British, Commonwealth and European Union citizens) living in Greater Manchester aged 18 or over on 4 May 2017 were entitled to vote in the mayoral election. The deadline to register to vote in the election was midnight on 13 April 2017.
