The City skipper beat off competition from Swansea's Jason Scotland, DJ Campbell from Blackpool and Brian Stock of Doncaster.
Chairman of the awards panel Chris Kamara said:
"Joe Ledley played out of his skin in January and it is little wonder that he was attracting interest from a number of Premier League clubs during the ransfer window. It is great news for Dave Jones' side that they were able to esist all offers for Joe as he is going to be instrumental in Cardiff's attempts to win promotion this season."
Well done Joe.
