Upper Leacock Township is a township in east central Lancaster County, Pennsylvania, United States. The population was 8,229 at the 2000 census. The township includes a village called Mascot, named by Annie Groff, a deceased member of the Ressler family, owners of the Mascot Roller Mills. She dedicated the name of the village to a canine actor she watched at a Broadway theatre show on her honeymoon. In 2005, the Lancaster Barnstormers baseball team introduced its mascot, Cylo, at the village's Mascot Roller Mills. The location was chosen for its lighthearted synonymity with the word mascot.
