Dungloe or Dunglow is a Gaeltacht town in County Donegal, Ireland. It is the main town in The Rosses and the largest in the Donegal Gaeltacht. Dungloe developed as a town in the middle of the 18th century, and now serves as the administrative and retail centre for the west of County Donegal, and in particular The Rosses, with the only mainland secondary school for the area.

There is a river at the bottom of the town and years ago the only crossing was over a grey granite slab lying in the riverbed, hence the Irish name of the town, An Clochan Liath, which means the grey stepping-stone. The bridge was built in 1782.

The name An Clochan Liath was formerly anglicised as Cloghanlea. The name Dungloe or Dunglow is believed to come from the Irish Dun gCloiche. This name came into common English usage in the later years of the 18th century when the monthly fair, formerly held at Dún gCloiche (five miles north of the nascent town) was transferred to An Clochan Liath. In time the name of the fair and that of the town were subsumed. Today, An Clochan Liath is the only officially recognised name of the town.
