10 Mount Morris Park is a prewar condominium building completed in 1923 in Harlem's historic Mount Morris Park district. Located at the southwest corner of West 121st Street and Mount Morris Park West, the seven-story building contains just eight residences. The intimate building sits directly across from Marcus Garvey Park, offering residents immediate access to the park's pool, playgrounds, basketball courts, dog run, and the Richard Rodgers Amphitheater, which hosts summer performances including Shakespeare in the Park and the annual Charlie Parker Jazz Festival.

Units feature Brazilian Cherry hardwood floors, central heating and cooling, recessed lighting, and in-unit washers and dryers. The building is dog friendly and benefits from a J-51 tax abatement through 2027, though there is an ongoing assessment of $304 per month. Apartments showcase high ceilings, with the penthouse boasting 11 foot ceiling heights, and many units offer multiple exposures that provide excellent natural light.

The building includes distinctive unit types, notably a maisonette duplex with dual private entrances on the landmarked townhouse block and a duplex penthouse with private elevator access. The penthouse spans over 1,700 square feet and features a large private terrace with 360 degree views of the Harlem and Midtown skylines, accommodating outdoor dining and lounging areas with electrical and water service. Both the maisonette and penthouse offer flexible lower level spaces suitable for recreation rooms, home offices, or additional sleeping areas, with the penthouse containing two non-adjacent king size bedrooms, each with ensuite bathrooms featuring deep soaking tubs.

The location provides convenient access to the 2 and 3 express trains, along with the 4, 5, and 6 lines, Metro North, and the M60 bus to LaGuardia. The neighborhood has evolved to include Whole Foods and Trader Joe's, alongside established restaurants like Red Rooster, Barawine, and Settepani. Cultural institutions nearby include the Apollo Theater, the National Jazz Museum in Harlem
