Great Connell Priory (Irish: Prióireacht Chonnail Mhór) is a former house of Augustinian canons dedicated to Saint Mary and Saint David,[1] situated on the eastern side of the River Liffey, in the Barony of Connell just to the south-east of the town of Newbridge, County Kildare, Republic of Ireland.

A statute of the Parliament of Ireland of 1475 authorised the Abbott to deal with Abbey's property in the "lands of the King's enemies" i.e. territories controlled by hostile Irish clans, without committing a crime as would otherwise be the case.

The Abbot was also permitted to enter contracts with the Irish for the purchase or sale of land and foodstuffs.

[1] Much of the original masonry was removed from the priory and used in the construction of the British Cavalry Barracks in Newbridge in the early 19th century.

At that time the top of the tomb of Walter Wellesley and some other fragments were discovered and built into the wall of the cemetery at the site.
