Middletown Township administrative offices are locate at 3 Municipal Way, Langhorne PA 19047; phone: 215‑750‑3800.
Known first as 'Middle Lots,' the township was formed in 1692. From 1703 to 1714 it was known as Middle Township. It was, in those days, at the middle of the then-settled area of the county. Some Quakers were already in the area prior to William Penn's arrival. The first Friends meeting was established in 1682 and the first meetinghouse was built in 1690.
Middletown contains vestiges of two historic villages: Bridgetown and Maple Point. Bridgetown is located at the confluence of Core Creek and Neshaminy Creek. The Maple Point settlement derived its name from the former Maple Point public school district. The original Maple Point schoolhouse was converted to a residence in the 1950s.
The Township is situated approximately midway between Philadelphia to the west and Trenton to the east. Middletown is adjacent to the Pennsylvania Turnpike, about 1.5 miles from Exit 351 (old Exit 28) and 2 miles from Exit 358 (old Exit 29). The Township is crossed by major traffic routes, including I-295, U.S. 1, and PA Route 413. These roads are convenient links to locations across the Delaware Valley and lead directly to the interstate highway system. Eleven municipalities border Middletown. These include the townships of Newtown, Lower Makefield, Falls, Bristol, Bensalem, Lowe Southampton, Northampton, and the four boroughs of Langhorne, Langhorne Manor, Penndel and Hulmeville.
The township is home to 5 county parks (Chicken Foot, Queen Anne, Frosty Hollow, Playwicki, and Core Creek) and 19 municipal/neighborhood parks (Middletown Community, Twin Oaks, Cobalt Ridge, Quincy Hollow, Upper Orchard, Forsythia Crossing, Lion's, Deep Dale, Delaware, Poplar, Harris, Sunflower, Detweiler, Veterans, Periwinkle, Beechwood, and Middletown Country Club.)
