Liadh Ní Riada was not present in Macroom District Court as Judge James McNulty heard that, on September 29, 2014, her car was observed travelling at a speed of 128km/h on the N22 Cork-Killarney road at Farran, Ovens.
Solicitor Sean Cahill, who represented the Ireland South MEP, said his client was unable to attend court, but wished to apologise for the incident.
Judge McNulty convicted and fined her €100.
Ms Ní Riada, of Ballymakeera, Co Cork, was elected to the European Parliament last year, winning the third of four Ireland South seats.
Meanwhile, former Laois footballer and Newstalk broadcaster Colm Parkinson appeared at the same court sitting, also for speeding.
The court was told Mr Parkinson’s car was observed travelling at 120km/h on September 13 last at Dereenaling, Ballyvourney.
The Off The Ball co-host told the court he was driving to Kerry and was “against the clock”, as he had taken a wrong turn on the way.
said he lives in Dublin, but that all his post goes to his address in Meelick, Portlaoise, and that the first he heard of the fine was when his mother called him to inform him of the summons to attend court.
Mr Parkinson insisted he would have paid the €80 fine, if only to spare himself a six-hour round-trip to Macroom to meet the charge.
He said he collects his post when he comes home every two weeks.
“With the washing?” Judge McNulty asked.
“No, I stopped doing that last year,” the 36-year-old jokingly replied.
Judge McNulty struck out the matter and instructed Mr Parkinson to make a €100 donation to the court poor box.
