Benjamin Harrison V (April 5, 1726 – April 24, 1791) is an American planter and revolutionary leader from Charles City County, Virginia.

He earns his higher education at the College of William and Mary, and he is perhaps the first figure in the Harrison family to gain national attention.

Harrison is a representative for Surry County, Virginia, (1756–1758) and Charles City County (1766–1776) to the House of Burgesses.

He is a Virginia delegate to the Continental Congress from 1774 to 1777 and, during the Second Continental Congress, is a signer of the Declaration of Independence.
