Mells Park is a country estate of 140 hectares near Mells, Somerset, England. It originated as a 17th-century deer park, probably created by the Horner family, who had been the owners of Mells Manor from 1543. The Horners expanded the park and planted extensive woodlands, resulting in a large collection of mature trees, especially 18th-century plantings of oak, lime and beech. The park is Grade II listed in the National Register of Historic Parks and Gardens. It contains Park House, also known as Mells Park House, a Grade II* listed building, built in 1925 in neoclassical style by the architect Edwin Lutyens, replacing an 18th-century house of the same name. It is c. 1 mile (1.6 km) west of Mells Manor House, which does not lie within the park.
