John Logan (1747 – July 1807) was a military officer, farmer and politician from Virginia who became a pioneer in and helped found the state of Kentucky. He served under his brother, Benjamin during Lord Dunmore's War in 1774, then both moved to what was then called Kentucky County, Virginia. Logan took part in several expeditions against the Shawnee, including some led by Daniel Boone, John Bowman, and George Rogers Clark. After Kentucky County was split into three counties, Logan and his brother at various times represented Lincoln in the Virginia House of Delegates, and John Logan also represented that county at the Virginia Ratification Convention in 1788.
