Sir Thomas Hallifax (23 February 1722 – 7 February 1789), associated with Gordon House in Enfield, Middlesex, was a prominent English banker who also held the positions of Lord Mayor of London and Member of Parliament.

The younger son of a clockmaker from Barnsley, Hallifax relocated to London where he began his career as a bank clerk. He advanced to the role of chief clerk before partnering with banker Joseph Vere and merchant Richard Glyn to establish Vere, Glyn & Hallifax Bank. This institution later evolved into Glyn, Mills & Co.. In 1766, he was appointed an alderman of London and subsequently served as Lord Mayor of London during 1776–77. He received knighthood on 5 February 1773.

Hallifax’s parliamentary career included a brief tenure as an MP for Coventry from December 1780 until February 1781, when he was removed following a petition. Later, he secured an uncontested seat representing Aylesbury, holding this position from 1784 until his passing in 1789.

At the time of his death in 1789, Hallifax's wealth was estimated at £100,000. He was married twice: initially to Penelope Thomson from Ewell, Surrey, and subsequently to Margaret Saville, daughter and coheiress of John Saville, a merchant based in Enfield. With Margaret, he fathered two sons, Thomas and Savile; Thomas later joined the banking partnership.
