Kilmore or Killmore ("the big church"), locally pronounced 'Kilmoor', is a village and townland in south County Wexford, Ireland, about 16 kilometres (9.9 mi) from Wexford town.

A tradition of carol singing in Kilmore, at St. Mary's Church, has taken place at Christmas time for over 200 years. The history of the Kilmore carols can be traced to the mid 18th century. The tradition was introduced to the parish by Very Rev. Peter Devereux, who was Parish Priest circa 1751. Some of the carols were written by Very Rev. William Devereux, P.P., Piercestown, a native of The Ring, Tacumshane, where he is buried. The remainder were written by Bishop Luke Waddinge of Ferns. In all, there are thirteen carols, eight of which are usually sung during the Christmas period, the first at first Mass on Christmas Day and the last one on Sunday nearest Twelfth Day. The singers consist of six local men and have traditionally included a member of the Devereux family, a tradition that is being continued to the present day. The singers divide into two groups of three and each group sings alternate stanzas.
