Clostoken or Cloghastookeen is a small townland in the civil parish of Kilconickny, near the town of Loughrea in County Galway, Ireland.

According to O'Donovan's Field Name Books (1862), the Irish language form of the name is Cloch stúincín, meaning "stone of the little prominence".

[1] Joyce (1910) writes "Near Loughrea in Galway, is a townland called Cloghastookeen, the stone fortress of the little pinnacle, which received its name from a castle of the Burkes, the ruins of which still remain.

There were three ecclesiastical parishes in the Middle Ages; Kilconickny (now Clostoken), Kilconieran and Lickerrig (now Carrabane).

[6] The Miller family of Cromwellian settlers inherited part of the Cloghastookeen estate through marriage with a Croasdaile heiress.
