And the big defender was presented with his award before training on Thursday morning.
Each month, the Club sponsor is running a competition for the Magpies' star man and giving fans the opportunity to present their hero with the award, simply by voting for their top performer.
Williamson was excellent in the wins over Chelsea, Tottenham, Norwich and West Brom to earn the prize.
United fan Stephen Evans from Dunston won the chance to present the 30-year-old with the Wonga trophy, as well as watching training and being given a Wonga Player of the Month pennant signed by Williamson.
Wonga will be running competitions every month throughout the season so check the Wonga Football fan hub regularly for your chance to win some great prizes: www.wongafootball.com/nufc.
