Ringaskiddy () is a village in County Cork, Ireland. It is located on the western side of Cork Harbour, south of Cobh, and is from Cork city, to which it is connected by the N28 road. The village is a port with passenger ferry, with two bi-weekly sailings to Roscoff in France. A ferry service to Swansea in Wales closed in 2012. During the 20th century, Ringaskiddy changed from a fishing village to a centre of transport and industrial activity. It is now one of the largest employment hubs in the pharmaceuticals sector in the region. The village is close to a number of tourist areas, including Crosshaven, Curraghbinny and Monkstown. A motorway project, to connect Cork city with Ringaskiddy, was given the "green light" by the supreme court in March 2021.
