Sir Thomas George Fermor-Hesketh, 5th Baronet (11 January 1825 – 20 August 1872) was an English Conservative politician who sat in the House of Commons from 1862 to 1872.

Hesketh was the only son of Sir Thomas Hesketh, 4th Baronet and his wife Annette Maria Bomford daughter of Robert Bomford of Rakinstown, co. Meath. In 1843 he inherited the baronetcy on the death of his father. He was educated at Christ Church, Oxford. He was a Deputy Lieutenant and J.P. for Lancashire and Northamptonshire and in 1848 was High Sheriff of Lancashire. He was lieutenant-colonel of the 6th Administrative Battalion of Lancashire Rifle Volunteers and colonel of the Duke of Lancaster's Own Militia. In 1862 Hesketh was elected Member of Parliament for Preston. He held the seat until his death at the age of 47 in 1872. In 1868 he assumed by royal licence the additional name of Fermor for himself and his second son following the death of his brother-in-law, the last Earl of Pomfret.

Hesketh married Lady Arabella Fermor sister and heiress of George Fermor, 5th Earl of Pomfret in 1846.
