The 27-year old landed the prize after scoring 21 league goals for the Lilywhites who sit second on the table in England's third tier.
The former Blackburn Rovers, Carlisle United, Nottingham Forest and Watford man beat MK Dons young gun Dele Alli and Bristol City's Luke Freeman to claim the prize at the Football League awards in London on Sunday night.
Preston Chief Executive John Kay, who collected the award on behalf of Joe Garner, said: "Joe is very important. He had to work hard when he joined the club and he established himself and started scoring goals.
"As he scored goals, we started getting results, so he was key. He is a talisman. When he was back fit you could tell there was a rise in the dressing room, in the lads and their confidence."
