The Archdiocesan Shrine of Señor Santo Niño is the Roman Catholic parish and archdiocesan shrine located in Midsayap, North Cotabato, Philippines. It is under the ecclesiastical jurisdiction of the Archdiocese of Cotabato. Santo Niño Parish is the oldest parish church established by the missionary congregation of the Oblates of Mary Immaculate in 1939.

The pioneering OMI priests took over the missionary territory of Cotabato which includes Midsayap which during that time covers Midsayap, Libungan, Pigcawayan, Alamada and Aleosan. It was initiated by a French-Canadian Oblate priest, Rev. Fr. Egide Beaudin, OMI to fortify the evangelization of Christian settlers in the locality who were mostly coming from Visayas and Luzon. Fr. Beaudin made frequent contacts with the faithfuls where he was able to learn the Cebuano language. Beaudin got help from the people to construct a worship place dedicated to the Child Jesus to whom most Cebuano settlers adored from their hometown of Cebu.

When the Second World War broke in 1941, the mission parish of Santo Niño was closed as turmoil reached Mindanao by invading Japanese forces. Foreign missionaries including the Oblates were put to concentration camps in the University of Santo Tomas and the University of the Philippines in Los Baños, Laguna.

After the war, the OMI priests went back to Midsayap to pursue the missioning to its people. American oblates took over the management of their mission stations including schools. Rev. Fr. Cuthbert B. Billman, OMI became the parish priest from 1945–1946. He was followed by Rev. Fr. Robert E. Sullivan, OMI from 1947-1948 which was also the time when the oblates established the first Notre Dame school in the Asia, the Notre Dame of Midsayap College. From 1949–1950, the parish was under Rev. Fr. Joseph Billman, OMI and assisted by Rev. Fr. Edward Gordon, OMI and Rev. Fr. Francis McSorley, OMI (who was later appointed as bishop-prelate of the Apostolic Vicariate of Jolo which covers the whole provinces of Sulu and Tawi-Tawi).

During the 1970s, the OMI congregation deemed it was time to slowly turn over the parish to Filipino priests by assigning them to large parishes such as Santo Niño. From 1970–1974, Rev. Fr. Donald Mundy, OMI commissioned a young Filipino oblate priest, Rev. Fr. Amador T. Castillo, OMI to work out major expansions in the parish by creating new chapels in the outskirts and remote barrios of Midsayap and Aleosan (which was part of the parish during that time).

For the period of 2001–2006, Rev. Fr. Edmundo Santoyo, OMI assisted by Rev. Fr. Danilo Sergio, OMI and the younger Rev. Fr. Jay Virador, OMI made large developments in the church renovation of the already old church.
