Andrew Allen (June 1740 – March 7, 1825) was a lawyer and official from the Province of Pennsylvania. Born into an influential family, Allen initially favored the colonial cause in the American Revolution, and represented Pennsylvania in the Second Continental Congress from 1775 to 1776. Like many other wealthy elites in Pennsylvania, however, he resisted radical change, and became a Loyalist after the Declaration of Independence and the Pennsylvania Constitution of 1776.
