Keachi Presbyterian Church is a historic Presbyterian church on Louisiana Highway 5 in Keachi in DeSoto Parish in northwestern Louisiana.It was built in 1858 in Greek Revival style and was added to the National Register in 1988. It was deemed to be "the finest" among merely seven country Greek Revival churches in the state of Louisiana, three of which happen to be in Keachi.Its portico with four Doric columns was enclosed in renovations in the 1890s, and the building's cupola appears to have been added then as well.
