St. Xavier's Senior Secondary School, Jaipur is a Christian minority school under the management of the Jesuits, an international Christian Religious Order, known as the Society of Jesus.

St. Xavier's School for boys was founded in July, 1941 under the name of St. Mary's Boy's School in the Roman Catholic Church Compound at Ghat Gate, Jaipur by Rev. Fr. Ignatius, O.F.M. Cap. In July 1943 its management was entrusted to the Jesuit Fathers, renowned for their educational work. The school was transferred to the present site and renamed St. Xavier's School in January, 1945, and still later as St. Xavier's Sr. Sec. School.

The Society of Jesus, founded by St. Ignatius of Loyola in 1540, has, since its origin, been active in the field of education throughout the world. In India, the Society of Jesus is at present responsible for more than one hundred high schools and 25 colleges in which over a lakh and a half, young people belonging to every creed, social class, community and linguistic group are educated through the medium of English and regional languages. These institutions are part of the Catholic Church's effort to share in the country's educational undertaking. This effort, while particularly responsible to the Christian community, has always been at the service of the whole nation. Thus in these institutions, recognised as Christian Minority Institutions, the religious beliefs of all students are treated with respect.
