The 2021 Alice Springs Town Council election were held on 28 August 2021 to elect a mayor and eight councillors to the Town of Alice Springs. The election was held as part of the local government elections held throughout the Northern Territory.
Matt Paterson was elected mayor with a two-candidate-preferred margin of just two votes. It was the closest-ever result in an election conducted by the Northern Territory Electoral Commission (NTEC).
Ahead of the 2020 Northern Territory general election, three Alice Springs councillors - Marli Banks, Eli Melky and Catherine Satour - joined the Australian Federation Party, with Melky as the party's NT leader. However, all three left the party by the time of the 2021 local elections.
Additionally, Matt Paterson was a Territory Alliance candidate, however he left the party around the time it dissolved following the 2020 election.
The mayoral election was decided by just two votes, the closest result that Northern Territory Electoral Commissioner Iain Loganathan said he had ever seen.
Unsuccessful candidate Jimmy Cocking requested a new recount, but it was rejected by the Northern Territory Civil and Administrative Tribunal in October 2021.
