A notice of voluntary dismissal was filed last month in Nevada state court.
According to reports, the filing didn't say whether the accuser had reached a settlement with the Portuguese player.
The New York Times reported in March that Juventus , the Italian league champions, wouldn't participate in the International Champions Cup in the US this summer to avoid the risk that Ronaldo would be detained by authorities as part of a rape investigation.
Ronaldo publicly denied the allegations and never filed a response to the lawsuit.
Leslie Stovall, a lawyer representing the woman who sued Ronaldo, didn't immediately respond to a request for comment on the dismissal.
