Saint Lawrence of Brindisi, O.F.M. Cap., (July 22, 1559, Brindisi, Apulia – July 22, 1619), born Giulio Cesare Russo, was a Catholic priest and a member of the Order of Friars Minor Capuchin.

Giulio was born in Brindisi, Kingdom of Naples, to a family of Venetian merchants. He was educated at Saint Mark's College in Venice, and joined the Capuchins in Verona as Brother Lawrence. He received further instruction from the University of Padua. An accomplished linguist, Lawrence spoke most European and Semitic languages fluently.

He was appointed Definitor General to Rome for the Capuchins in 1596; Pope Clement VIII assigned him the task of converting the Jews in the city. Beginning in 1599, Lawrence established Capuchin monasteries in modern Germany and Austria, furthering the Counter-Reformation and bringing many Protestants back to the Catholic faith.

In 1601, he served as the imperial chaplain for the army of Rudolph II, Holy Roman Emperor, and successfully recruited Philippe Emmanuel, Duke of Mercœur to help fight against the Ottoman Turks. He then led the army during the capture of Székesfehérvár in Hungary from the Ottoman Empire, armed only with a crucifix.

Brindisi (Italian pronunciation: [ˈbrindizi] ( listen); Sicilian: Brìnnisi; Latin: Brundisium) is a city in the Apulia region of Italy, the capital of the province of Brindisi, off the coast of the Adriatic Sea. Historically, the city has played an important role in commerce and culture, due to its position on the Italian Peninsula and its natural port on the Adriatic Sea. The city is a major port for trade with Greece and the Middle East. Brindisi has an active industry in agriculture, chemical and energy production.

Brindisi is situated on a natural harbor, that penetrates deeply into the Adriatic coast of Apulia. Within the arms of the outer harbor islands are Pedagne, a tiny archipelago, currently not open and in use for military purposes (United Nations Group Schools used during the intervention in Bosnia). The entire municipality is part of the Brindisi Plain, characterized by high agricultural uses of its land. It is located in the northeastern part of the Salento plains, about 40 km (24.85 mi) from the Itria Valley, and the low Murge. Not far from the city is the Natural Marine Reserve of the World Wide Fund for Nature of Torre Guaceto. The Ionian Sea is located about 45 km (27.96 mi) away.
