Patrick Lynch (1715–1789) was an Irish emigrant who became a significant landowner in Rio de la Plata, which is now part of Argentina.

Biography
He was born in Galway and was the second son of Captain Patrick Lynch of Lydican Castle and Agnes Blake. The Lynches and the Blakes were two of the 14 tribes of Galway, who dominated the political, commercial, and social life of the city of Galway in western Ireland between the mid-13th and late-19th centuries. The Lynches left Ireland after their defeat at the hands of Cromwell's forces and later those of William of Orange. Patrick left in the 1740s for Bilbao, Spain, and travelled from there to Rio de la Plata, where he was appointed "regidor" (royal representative) and captain in the "Milicias". In 1749 he married Rosa de Galayn y de la Camara, a wealthy Argentinian heiress. His eldest surviving son, Justo Pastor Lynch who was a customs official under Viceroy Cisneros, also a captain and regidor, inherited Captain Lynch's vast land holdings.
