The Mariemont Historic District is a National Historic Landmark District encompassing most of the municipality of Mariemont, Ohio, USA. Mariemont was planned and developed in the 1920s by philanthropist Mary Emery and landscape architect John Nolen, and was one of the nation's first planned suburban communities. Its architecture and streetscape are still strongly evocative of its original plans. A large portion of the community was listed on the National Register of Historic Places in 1979; a larger area (fully encompassing the first listing) was designated a National Historic Landmark (as Village of Mariemont) in 2007.
