The Ralli Baronetcy, of Park Street in the City of Westminster, is a title in the Baronetage of the United Kingdom. It was created on 8 February 1912 for Lucas Ralli, head of the firm of Ralli Brothers, who were financiers, shippers, cotton and grain merchants. The Ralli Family are of Greek origin, and are ultimately descended from the Frankish-Byzantine Raoul/Ralles Family. Originally from the Greek island of Chios, due to the Chios massacre the Ralli family was forced to emigrate to the United Kingdom, where they founded the eponymous firm.
