St. Patrokli is a Roman Catholic parish and church in Soest, Germany. The church is of great significance in the history of architecture as it is the epitome of Romanesque architecture in Westphalia. As a result, it is known as St.-Patrokli-Dom (St. Patroclus' "Cathedral"). It holds relics of its patron saint Patroclus of Troyes from 954. It was the church of the canonical foundation of St. Patroclus, which existed from the 10th century until its abolition in 1812. Since 1823 the church has been the parish church of the St. Patrokli parish in the diocese of Paderborn. In 1859 it was promoted to the rank of provost church.
