The Oude Kerk (English: Old Church) is a Reformed church in Amsterdam, Netherlands, being the oldest parish church in the city. The oldest structure in Amsterdam, the building was founded around 1213 and consecrated in 1306 as a Roman Catholic church by the bishop of Utrecht with Saint Nicolas as its patron saint. After the Reformation in 1578, it became a Reformed (Calvinist) church, which it remains today. It is located in De Wallen and since 2012, the church has also housed contemporary art exhibitions. The square surrounding the church is the Oudekerksplein.
