St. Francis Xavier's Cathedral is the cathedral of the Roman Catholic Archdiocese of Bangalore in India. Initially, Bangalore was the seat of the diocese of Mysore from 1886 to 1940 and during this time, St. Patrick's church in Bangalore was the cathedral of the diocese. When the diocese of Mysore was bifurcated on 13 February 1940 to form the diocese of Bangalore, St. Francis Xavier's church was chosen as its cathedral.
