Jaro, officially the District of Jaro, is one and the largest of all the seven districts of Iloilo City, in the province of Iloilo, on the island of Panay, in the Western Visayas region of the Philippines. Once a separate city, it merged when Iloilo City was re-incorporated in the 1940s during the American administration in the Philippines. Jaro is the largest of all the seven districts comprising the City of Iloilo. The Iloilo City district of La Paz and the present municipalities of Leganes and Pavia, adjoined as historical parts of Jaro before they became independent.
Jaro lends its name to the Roman Catholic Archdiocese of Jaro, the metropolitan see which encompasses the provinces of Antique, Guimaras, Iloilo, and Negros Occidental.
The Jaro annual Catholic feast of Nuestra Señora de la Candelaria, the Roman Catholic patron of the whole Western Visayas and Romblon, held every February 2, is one of the well known marian festivals in the Philippines. The statue or image of Candelaria perched atop the facade of the Jaro Cathedral, is the first marian image crowned personally without a papal legate by a Pope and Saint in the Philippines and in Asia, by Pope John Paul II in 1981.
