Chadds Ford Township is a township in Delaware County, Pennsylvania, about 25 miles (40 km) southwest of Philadelphia. Prior to 1996, Chadds Ford Township was known as Birmingham Township; the name was changed to allow the township to correspond to both its census-designated place and to distinguish itself from the adjacent Birmingham Township in Chester County. As of the 2010 census, Chadds Ford Township had a population of 3,640, up from 3,170 at the 2000 census.
Chadds Ford was home to N.C. Wyeth, his son Andrew Wyeth, and grandson Jamie Wyeth. The Brandywine Battlefield (site of the Battle of Brandywine) is located in the township, along with the Brandywine River Museum, which houses much of the Wyeth collection. Weldon Brinton Heyburn (1852–1912), a U.S. senator from Idaho, was born in Chadds Ford.
