General Sir Frederick Adam GCB GCMG (17 June 1781 – 17 August 1853) was a Scottish major-general at the Battle of Waterloo, in command of the 3rd (Light) Brigade.

He was later a Lord High Commissioner of the Ionian Islands, who built Mon Repos, Corfu and other important landmarks in that Protectorate.

He took part in the campaigns in the Netherlands and Egypt under Sir Ralph Abercromby, he was promoted to the rank of major in 1803 and a lieutenant colonel in 1804.

On 12 April 1813, while commanding the Light Brigade in John Murray's expeditionary force, Adam led a brilliant rearguard action against the corps of Marshal Louis-Gabriel Suchet at Biar.

But a charge from Adam's brigade threw them into a state of confusion and those which were left retreated towards La Belle Alliance.

General Adam's Brigade charged the square which was formed on rising ground to the (British) right of La Belle Alliance and again threw them into a state of confusion.
