The Glen, Cork, Residential area in northern Cork, Ireland.

The Glen is a residential neighborhood on a hillside in northern Cork, with social housing estates located near Glen River Park. The area follows an ancient glacial valley formation that shapes its natural landscape.

In the 1850s W. and H.M. Goulding built a large factory in The Glen to make phosphate fertilizers, and the area became known as Goulding's Glen. The factory closed and was demolished in the mid-20th century, leaving very little. Sir Basil Goulding donated the land to the people of Cork in the late 1960s, and it was developed as an amenity park.

The name An Gleann comes from the Irish for "the valley", referring to the glacial valley the area surrounds. Frank O'Connor's story "The Ugly Duckling" describes a man returning to walk up Goulding's Glen, finding the old mill pond dried up and recalling winter skaters and summer stars on it. The Glen River still flows east–west through the park.

The Glen lies south of the Glen River valley, with the amenity park reached from the housing estates along its edge. Two tunnel ventilation shafts stand in the area, one on Arderin Way and one on Glentrasna Drive. Blackpool Shopping Centre and its retail park are nearby to the north.

The railway tunnel beneath The Glen was built between 1847 and 1855 to link Mallow with Cork city. Two of its four ventilation shafts stand in the neighbourhood, at Arderin Way and Glentrasna Drive.
