Hexham Abbey is a place of Christian worship dedicated to St Andrew and located in the town of Hexham, Northumberland, in northeast England. Since the Dissolution of the Monasteries in 1537, the Abbey has been the parish church of Hexham.

There has been a church on the site for over 1300 years since Etheldreda, Queen of Northumbria made a grant of lands to Wilfrid, Bishop of York c.674. Of Wilfrid's Benedictine abbey, which was constructed almost entirely of material salvaged from nearby Roman ruins, the Saxon crypt still remains; as does a frith stool, a 7th/8th century cathedra or throne. For a little while around that time it was the seat of a bishopric.

In the year 875 Halfdene (Halfdan Ragnarsson) the Dane ravaged the whole of Tyneside and Hexham Church was plundered and burnt to the ground.

About 1050 one Eilaf was put in charge of Hexham, although as treasurer of Durham, he probably never came there. Eilaf was instructed to rebuild Hexham Church which then lay in utter ruin. His son Eilaf II completed the work, probably building in the Norman style.

Hexham Abbey originated as a monastery founded by Saint Wilfrid in 674. The crypt of the original monastery survives, and incorporates many stones taken from nearby Roman ruins, probably Coria or Hadrian's Wall. The current Hexham Abbey dates largely from the 11th century onward, but was significantly rebuilt in the 19th century. Other notable buildings in the town include the Moot Hall, the covered market, and the Old Gaol.
