Crichton Castle is a ruined castle near the village of Crichton in Midlothian, Scotland. It is situated at the head of the River Tyne, 2 miles (3.2 km) south of the village of Pathhead, and the same distance east of Gorebridge.

James Hepburn, 1st Duke of Orkney and 4th Earl of Bothwell, better known simply as Lord Bothwell, was a prominent Scottish nobleman. He was known for his marriage to Mary, Queen of Scots, as her third and final husband. He was accused of the murder of Mary's second husband, Henry Stuart, Lord Darnley, a charge of which he was acquitted. His marriage to Mary was controversial and divided the country; when he fled the growing rebellion to Norway, he was arrested and lived the rest of his life imprisoned in Denmark.
