Ouderkerk aan den IJssel (Dutch pronunciation: [ˌʌudərkɛr(ə)k aːn də(n) ˈɛisəl]; English: Ouderkerk upon IJssel) is a village in the municipality of Krimpenerwaard, in the province of South Holland, the Netherlands.

Of these, Ouderkerk aan den IJssel is the largest population centre and the location of the town hall.

The town is named for its "old church", which was a prominent landmark for centuries on the horizon for ships travelling along the IJssel river.

Remains of a tuff stone church foundation from that same century have been found.

Henry de Nassau, Lord Overkirk, an army leader during the Spanish War of Succession, is buried in the main church.
