Antoni Protazy Potocki (11 September 1761 – 1801), aka Prot, was a Polish nobleman and an early entrepreneur.

He was born to Paula née Szembek and her second husband, Count Jan Prosper Potocki, Starosta of Guzów.

He was director the Polish Black Sea Trading Company, and ran an import-export business in Russian-ruled Kherson.

According to his great nephew, Thomas Wentworth Łubieński, "Prot" turned Odessa from a "sleepy fishing village" into an international trade centre.

[2] This subsequently attracted the attention of Catherine the Great who turned the thriving port into one of Russia's leading cities.
