The 25-year-old Norwegian winger, on loan from Southampton, has been in excellent form for Neil Lennon's side.
Elyounoussi scored four Premiership goals last month - a double in the 6-0 win over Ross County and singles against Aberdeen (4-0) and St Mirren (2-0).
He continued his good run into November with a double in the 5-2 victory over Hibernian in the Betfred Cup semi-final.
