The Hibernian forward wins the division's top individual accolade after scoring 23 goals this season, including a 35-yard free kick in Sunday's Edinburgh derby victory
The 22-year-old is on his second season-long loan from Wolves and talks have been held between Hibs and the now-relegated Championship outfit over a possible permanent transfer for the striker, who won his first Scotland cap in November.
Griffiths, who netted a 35-yard free kick in an Edinburgh derby win over Hearts on Sunday, had previously picked up the SFA Young Player of the Year award but bizzarely missed out on Hibernian's internal prize, which instead went to goalkeeper Ben Williams.
The other winners on the night were Stuart McCall of Motherwell, who took the Manager of the Year award home, and Victor Wanyama of Celtic, who was hailed the league's Young Player of the Year.
Hoops boss Neil Lennon had criticised the shortlist following its April announcement, which included none of his title-winning squad.
