St Peter's Roman Catholic Church is a large mid-nineteenth century church in Buckie, Moray, Scotland. Known locally as the Buckie Cathedral, it was built between 1851 and 1857, soon after the emancipation of Catholics in Scotland, to provide a place of worship for the local Catholic congregation. It was designed by James Kyle, Catholic bishop of Aberdeen, and built on land donated to the diocese by Sir William Gordon, Baronet of Letterfourie. It was extended and redecorated in the early twentieth century by Charles Ménart, and was designated a Category A listed building in 1972. It remains an active place of worship, under the governance of the Roman Catholic Diocese of Aberdeen.
