Seal of Bucks County, Pennsylvania

The traditional seal of Bucks County, Pennsylvania takes its design from the inspiration of the county's founder, William Penn. The center of the seal consists of a shield from the Penn family crest with a tree above and a flowering vine surrounding it in symmetric flanks. The seal has a gold-colored background and a green band denoting Penn as the county's first proprietor and governor.

In 1683, Penn's council decreed that a tree and vine be incorporated into the emblem to signify the county's abundance of woods. The seal was used in its official capacity until the American Revolutionary War. The county government has since used the official Pennsylvania state seal for official documents.

Today, the Bucks County seal's use is largely ceremonial. It appears on county stationery and vehicles as a symbol of the county's heritage. The gold emblem is also the centerpiece of the official Bucks County flag, which has a blue background and gold trim.
