St. John's Catholic Church, built in 1915, is a historic Carpenter Gothic style Roman Catholic church building located in Paxton, Dickens Township near Dallas, South Dakota, United States. Its steep roof, lancet windows and belfry and entrance are typical of Carpenter Gothic churches. In 1973 it was closed but a year later it was given to a group of former parishioners who agreed to maintain it and its adjoining cemetery. The church and the cemetery are the only remnants of the former community of Paxton.

On November 20, 2009, the church was added to the National Register of Historic Places.
