Athelney Abbey, established in the county of Somerset, England, was founded by King Alfred in 888, as a religious house for monks of the Order of St. Benedict.

Originally Athelney was a small island in swampland, in what is now the parish of East Lyng, covered with alders and infested by wild animals.

The original church was a small structure, consisting of four piers supporting the main fabric and surrounded by four circular chancels.

An indulgence of thirty days was given in 1321 for those who should assist in the rebuilding of the church, and the monks petitioned Edward I of England to remit corrody for which they were unable to find the means of payment.

With eight monks of his community, he surrendered February 8, 1540, receiving a pension of £50 per annum and retaining his prebend of Long Sutton.
