Twitter user Mel posted the video to the social networking site shortly after the Hoops beat County 1-0 in their early Scottish Premiership clash in Dingwall.
It had been a pretty dire affair before Griffiths stepped up to the 30-yard free-kick shortly after coming on as a second-half substitute.
But he lit the game up with a curling beauty of a striker that gave Staggies goalie Aaron McCarey absolutely no chance.
The TV footage of Griffiths’ goal is brilliant, but the fan cam might be even better given it includes the mad scenes from the Celtic fans:

That is an absolute stunner – and is sure to be shared hundreds of times once the majority of fans get a look at it.
The goal gave Celtic the win and a six-point lead at the top of the Premiership going into Aberdeen’s 3pm clash with Motherwell.
