Honey Brook is a borough located in Chester County, Pennsylvania, United States. The population of the borough was 1,713 at the 2010 census.
Honey Brook Township was divided from Nantmeal Township in 1789. A schoolmaster and land developer named Stinson bought a plot of land along Horseshoe Pike in 1815. He had it surveyed and held a lottery to sell the lots for the town he called Waynesborough in honor of the Revolutionary War general, Mad Anthony Wayne. The residents changed the name to Honey Brook in 1884. Honey Brook is an incorrect English translation of the Welsh Nantmel, a village in Radnorshire, now part of Powys. The name 'Nantmel' actually means 'Mael's valley', Mael being a tenth-century prince. Honey Brook was incorporated as a borough in 1891.The year 1884 brought more changes to the village and township. The railroad from Philadelphia-Downingtown-Lancaster was completed and ran along the south side of Horseshoe Pike. As the town grew, a petition was circulated in 1891 for the town to be incorporated into a borough. Almost every homeowner signed. With the incorporation as a borough, the main problems to overcome were: street lighting, sidewalks, and several years later, water.
