The Philadelphia Society for Promoting Agriculture was organized February 11, 1785 by a group of twenty-three farmers, merchants and professional people for the purpose of exchanging crop and animal production information among members and with other regional agricultural societies. The Philadelphia Society for Promoting Agriculture is the oldest, continuously active, agricultural organization in the United States.

The Society is a non-profit, non-partisan organization whose mission is to help its members and the general public develop well informed opinions with respect to the policies, achievements and concerns of U.S. agriculture.
