Where Kentucky is

Kentucky lies south of the Ohio River, where the Upper South meets the Midwest. It stretches about 380 miles east to west and 140 miles north to south, tapering to a narrow point at the confluence of the Ohio and Mississippi. Indiana, Ohio and Illinois lie across the Ohio River to the north, West Virginia to the east, Virginia to the southeast, Tennessee to the south, and Missouri to the west across the Mississippi. Louisville is on the Ohio in the north-central part of the state, Lexington in the Bluegrass region to its east, and Frankfort between them on the Kentucky River.

Geography

Borders

The Ohio River border is natural and dates from Virginia's 1784 land cession: Kentucky owns the river up to the northern low-water mark as it stood in 1792, so islands and the water belong to Kentucky. The Mississippi, Big Sandy and Tug Fork rivers form the western and north-eastern borders. The Virginia border follows the crest of Cumberland Mountain and Pine Mountain. The long Tennessee line was meant to follow 36°30′N but the 1779–80 Walker survey drifted several miles north, and later corrections left the border with a visible jog near the Tennessee River.
