Peter Michael Murphy (born 27 October 1980, in Dublin) is an Irish football player and coach, who is the current manager of Scottish League One club Queen of the South.

He then went on to play for Blackburn Rovers, Halifax Town (on loan, scoring his first career goal in a match against Kidderminster Harriers)[2] and Carlisle United.

While at Brunton Park Murphy started 400+ games and scored the winning goal in the Conference National Playoff Final 2005, which ensured The Cumbrians return to the Football League.

[15] This appearance meant he became first Carlisle United player to win full international honours while with the Brunton Park club since Eric Welsh, who won four caps for Northern Ireland in the 1960s.

On 9 May 2024, Annan Athletic announced that Murphy had left the club to join fellow Scottish League One side, and local rivals, Queen of the South.
