Malachy Postlethwayt (1707? – 1767) was a British commercial expert famous for his publication of the commercial dictionary titled The Universal Dictionary of Trade and Commerce in 1757. The dictionary was a translation and adaptation of the Dictionnaire universel du commerce of the French Inspector General of the Manufactures for the King, Jacques Savary des Brûlons.

Postlethwayt wrote several works on the benefits to the British economy from the African slave trade to the colonies in North America.
