St Lambert's Church is a Roman Catholic church building in Münster in Germany, dedicated to Lambert of Maastricht. Its present building is the most significant example of Westphalian late Gothic architecture. It lies on the north side of the Prinzipalmarkt in the city centre. Until the early 20th century, the Roggenmarkt contained the Drubbels district of housing. To the church's east lies the Alte Fischmarkt and the Salzstraße, whilst between the church and the Salzstraße is the Lambertikirchplatz with the Lambertibrunnen.
Three iron baskets hang from the church tower – in 1536 these were used to expose the corpses of Jan van Leiden, Bernhard Krechting and Bernhard Knipperdolling after they were publicly tortured and killed in the Prinzipalmarkt for leading the Münster Rebellion. In 2007 the twentieth episode of the TV-series Wilsberg, 'Die Wiedertäufer', was filmed at the church.
