General Sir Thomas Hawker KCH (1777 – 13 June 1858) was a British Army cavalry officer.

Hawker served in the force sent to occupy the Republic of Genoa in 1814 and shortly after was promoted to colonel and given command of a light cavalry brigade.

Spending some time on half pay after the end of the Napoleonic Wars he returned to active service as lieutenant-colonel of the 13th Light Dragoons.

[8] On 1 December 1804, he purchased the rank of major in the 20th Light Dragoons with which he served in the Mediterranean and Spain during the Peninsular War from 1805 to 1814.

[11] Accompanying the expedition to the Gulf of Genoa in April 1814, Hawker was given the brevet rank of Colonel in June and given command of the light cavalry brigade; in 1815 the brigade joined an Anglo-Austrian force intended to depose Joachim Murat, the King of Naples, but the mission was abandoned after Murat's defeat.

[12] After the Napoleonic Wars he spent some time on half pay before returning to the army, on 9 August 1821, as lieutenant-colonel of the 13th Light Dragoons.

[3] A monument in St Mary the Virgin's Church, Bathwick in Somerset, records the death of Hawker's first wife, "who died at sea on her return from India, March 21st 1836".

[25][26][27][28] In 1838 he married the eldest daughter of William Woodley, the widow of Frederick Noel, a Royal Naval captain.
