Duke of Hamilton is a title in the Peerage of Scotland, created in April 1643. It is the senior dukedom in that peerage (except for the Dukedom of Rothesay held by the sovereign's eldest son), and as such its holder is the premier peer of Scotland, as well as being head of both the House of Hamilton and the House of Douglas. The title, the town of Hamilton in Lanarkshire, and many places around the world are named after members of the Hamilton family. The ducal family's surname, originally "Hamilton", is now "Douglas-Hamilton". Since 1711, the dukedom has been held together with the Dukedom of Brandon in the Peerage of Great Britain, and the dukes since that time have been styled Duke of Hamilton and Brandon, along with several other subsidiary titles.
