Lieutenant-General Lord Frederick FitzClarence, GCH (9 December 1799 – 30 October 1854) was a British Army officer as well as being the illegitimate third son of King William IV and his mistress, Dorothea Jordan.

FitzClarence was commissioned as an officer in the British Army in 1814. While a captain in the Coldstream Guards, FitzClarence commanded a small detachment of Guards to act in support of the police with the arrest of the Cato Street conspirators in 1820. The arrest was not straightforward, and a scuffle ensued. The Naval and Military Gazette (May 1845) identified Sgt James Graham as the man who saved FitzClarence's life.

Frederick FitzClarence gained the rank of Colonel in the service of the 36th (Herefordshire) Regiment of Foot. On 24 May 1831 he was granted the rank of a marquess' younger son. Having been invested as a Knight Grand Cross of the Royal Guelphic Order (G.C.H.) that same year, he became Lieutenant-Governor of Portsmouth and General Officer Commanding South-West District in 1847 and then Commander-in-Chief of the Bombay Army in 1852. He died in office in October 1854.

On 19 May 1821, he married Lady Augusta Boyle (d. 28 July 1876), the eldest daughter of the 4th Earl of Glasgow. They had two children:
