John Longmire has been the senior coach of the Sydney Swans since 2011. Longmire led the football club to the 2012 Premiership and two further Grand Final appearances in 2014 and 2016.

The Sydney Swans have missed just one finals series under the guidance of Longmire since he took over. 

In 2020 Longmire will be joined by John Blakey, Dean Cox, Brett Kirk, Steve Johnson, Jarrad McVeigh and Tadhg Kennelly in the coaches box. Lloyd Perris and Jeremy Laidler will continue to look after the Clubs development program.
