The woman's mother has also filed a separate, smaller claim at the High Court in Dublin.
Irish Police previously investigated the allegations, but no action was taken, reports the Mirror.
In a statement given to the Irish Independent, Mr McGregor’s spokesperson Karen J Kessler said: “After an exhaustive investigation conducted by the Gardaí which, in addition to interviews of the plaintiff, included interviewing numerous sources, obtaining witnesses' statements, examining closed-circuit footage and the cooperation of Conor McGregor, these allegations were categorically rejected.
“The plaintiff knows the facts contradict the assertions in this lawsuit.
"Mr McGregor will dispute any claims and is confident that justice will prevail.”
McGregor is currently in Abu Dhabi preparing to face Dustin Poirier on Sunday morning.
The rivals first met in 2014 when McGregor needed less than two minutes to win by stoppage.
He went on to win first the featherweight and then the lightweight title before taking on Floyd Mayweather in the second-richest fight of all time.
