Goodwillie won the young player prize, with a panel of "football experts" agreeing with Scotland's professional footballers.
Goodwillie, 22, claimed the award for the second year running after hitting 16 SPL goals so far.
He said: "It's been a great few days for me. I wasn't really expecting this so I'm just really happy and surprised.
"It's good that people are still noticing me playing well and that's the only thing I want to concentrate on right now."
