Alan Richard Knill (born 8 October 1964) is a professional football manager and former player, who is a coach for the Wales national team and Sheffield United.

With eight games remaining, and only one point from the play-offs, Alan Knill left Bury to join Scunthorpe United on 31 March 2011.

[8] After a difficult start to the 2012 season, Knill believed that life had been put into perspective after narrowly avoiding serious injury after a crash with a squirrel.

[10] On 20 February 2013, Torquay United appointed Knill as caretaker manager in place of Martin Ling, who had gone on sick leave.

Knill's objective was to keep The Gulls in the football league and that was achieved on the final day of the season with a 3–3 draw at home to Bristol Rovers.

[15] In March 2023, Knill joined Championship side Watford, again working as assistant to Wilder, the newly appointed head coach.
