Hume Castle is the heavily modified remnants of a late 12th- or early 13th-century castle of enceinte held by the powerful Hume or Home family, Wardens of the Eastern March who became successively the Lords Home and the Earls of Home. The village of Hume is located between Greenlaw and Kelso, two miles north of the village of Stichill, in Berwickshire, Scotland.. It is a Scheduled Ancient Monument, recorded as such by Historic Environment Scotland.

Clan Home is a Scottish clan. It held immense power for much of the Middle Ages and dominated the eastern Scottish Borders. It produced no fewer than eight Wardens of the Eastern March – more than any other family.
