The Basilica of the Holy Apostles (German: Basilika St. Aposteln, German pronunciation: [ˌzaŋt ʔaˈpɔstl̩n], Colognian pronunciation: [ˌtsɪnt ʔaˈpɔsˑtəl]) is a Romanesque church in Cologne (Köln), located near Innenstadt's busy Neumarkt (Köln) [Wikidata]. The former collegiate church is dedicated to the twelve Apostles. It is one of the twelve Romanesque churches built in Cologne in that period.

The church has a basilical plan of nave and aisles, and like Groß St. Martin and St. Maria im Kapitol, has three apses at the east end making a trefoil plan. There is a single tower of 67 metres at the west.
