St. Joseph's Church Complex, Catholic institutional complex in Fort Madison, United States.

St. Joseph's Church Complex is a cluster of buildings in downtown Fort Madison that includes a Gothic Revival church, rectory, chapel, convent, and former school structure. The buildings occupy a cohesive block and reflect different construction phases and architectural approaches from their respective time periods.

The parish was founded in 1840 by missionary priest John George Alleman for a small group of Catholic families in the area. The community grew rapidly, leading to construction of a larger church building that opened in 1847.

The parish was long known as the German Catholic Church because so many of its members were German; in January 1874 it received its own pastor at the original location. The parish name was carried into Saints Mary and Joseph Parish after the 1996 merger.

The former church, chapel, rectory, convent and school stand together on the east side of downtown Fort Madison and are contributing properties to the Park-to-Park Residential Historic District, listed on the National Register in 2014. St. Joseph's Church closed in 2007, so the buildings are not open as an active parish; view them from the street as part of a walk through the district.

The parish was organized in 1840, and its first church was a small brick building put up with help from John Gerhard Schwartz, in whose home John George Alleman had said Fort Madison's first Mass. The 1886 church that still stands replaced the 1847 building.
