Eyrecourt Castle (or Eyre Court) was an Irish 17th century country house in Galway which became a ruin in the 20th century. The house, the surrounding estate, and the nearby small town of Eyrecourt all took their name from Colonel the Right Hon. John Eyre, an Englishman who was granted a large parcel of land in recognition of his part in the military campaign in Galway during the Cromwellian conquest of Ireland. There was an earlier fortified house or castle on the same land.
There is also a block of private apartments called Eyre Court located in the London neighbourhood of St. John's Wood.
