The conference announced the fine Monday.
Hurley was reprimanded for following and verbally abusing officials as they exited the court after the Beavers beat the Sun Devils 75-68 on Saturday night in Corvallis.
Hurley responded to every media question after the game with: "I'm a terrible coach right now.''
Pac-12 Commissioner Larry Scott said in a statement Hurley violated conference policy and that type of behavior will not be tolerated.
Hurley was also reprimanded by the Pac-12 in January for his public comments about officiating after a loss to Colorado.
