Katarapko Campsite 19 is a group site situated along Katarapko Creek in South Australia, part of a larger network of campsites that stretches from the Murray River through to the creek.

It sits beside a low-water causeway (weir) that crosses Katarapko Creek, offering pedestrian access to the adjacent island during periods of low flow.

The original stone weir dates to around 1908 and was built primarily to support river navigation and local agriculture.

The creek is generally quiet, as submerged trees limit boat navigation to a kilometer or two, meaning most watercraft passing the site are canoes or kayaks. All campsites in the Katarapko area must be booked in advance through Parks SA.
