McGeady was caught driving his Audi Q7 4x4 at 54mph in a 30mph area in February last year.
McGeady, 24, was fined and had four points put on his licence at the Justice of the Peace Court in Glasgow.
He had denied speeding along Carmunnock Road in Glasgow on 15 February, 2009 but was found guilty by Justice of the Peace Eunice Paton after a four-day trial.
McGeady's lawyer, Terry Gallanagh, argued that the police had not corroborated McGeady's identity, or proved that the alleged offence happened on a restricted road.
The court heard how McGeady already had seven live points on his licence and had one previous conviction for a road traffic offence from 2006.
The footballer made no comment as he left but Mr Gallanagh said his client would appeal against his conviction.
He told reporters: "We are going to lodge an appeal which will relate to matters of law and will also relate to the conduct of the trial".
