The Roman Catholic Archdiocese of Tuguegarao is a Latin Church metropolitan archdiocese of the Catholic Church in the Philippines. Tuguegarao is a river delta city that became center of the archdiocese in the province of Cagayan, on the island of Luzon. Its seat is located at the Saint Peter the Apostle Metropolitan Cathedral.

The Metropolitan Archdiocese of Tuguegarao, the present territorial jurisdiction of the Archdiocese of Tuguegarao covers the entire province of Cagayan.

The missionaries of Order of Preachers first evangelized Cagayan in 1595. They brought not only the tenets of Christian faith but also western technologies, infrastructures and ideas that helped in the livelihood and welfare of the Cagayanos. The Church of Saint Peter was constructed in 1761. It later became the diocesan cathedral.^[2]

The Diocese of Tuguegarao was created April 10, 1910^[3] with decree of the Congregation of the Sacred Consistory "Nova Diocesum Circumscriptio In Insulis Philippinis". At the time of its foundation until 1951, its territorial jurisdiction stretched from the Batanes to Nueva Vizcaya.

The first bishop of Tuguegarao was Bishop Maurice P. Foley and he took possession of his diocese on December 6, 1911. He convoked the first Diocesan Synod of Tuguegarao from April 16–19, 1912. After his appointment as bishop of Jaro, he was succeeded by Bishop Santiago C. Sancho as the second bishop of Tuguegarao. He established the San Jacinto Seminary in 1980 in order to cater to the formation of native clergy and it was given to the administration of Dominicans of the Collegio de San Jacinto. He convoked the second Diocesan Synod of Tuguegarao from April 12–14, 1923.

Sancho was appointed bishop of Nueva Segovia in 1927 and he was succeeded by Bishop Constant J. Jurgens as the third bishop of Tuguegarao.^[4] He was regarded as the "Teaching Bishop" because of his priority for education as a tool for evangelization. He also promoted catechism for children and the devotion to the blessed Mother in his diocese. He convoked the third Diocesan Synod of Tuguegarao from August 27–28, 1935. Jurgens was the bishop of Tuguegarao during the Second World War.

He re-opened the San Jacinto Seminary as a minor seminary 18-years after it was closed by his predecessor in 1932. Olalia took part in the First Plenary Council of the Philippines in 1953. Upon his appointment as bishop of Lipa, a four-year vacancy ensued the diocese. The auxiliary bishop of Nueva Segovia, Juan C. Sison, served as apostolic administrator. There were significant events that occurred in those 4 years. On June 20, 1954, the image of Our Lady of Piat was canonically crowned by the Apostolic Nuncio to the Philippines, Archbishop Egidio Vagnozzi at the patio of the St. Peter's Cathedral. He also built the present residence and offices of the bishop of Tuguegarao.

In 1957, Teodulfo S. Domingo was appointed as the fourth bishop of Tuguegarao and he was the first native of Cagayan to be consecrated as bishop. Domingo took part in all the session of the Second Vatican Council and he was a witness to the early years of the implementation of council's reforms in the diocese of Tuguegarao. On September 21, 1974, Tuguegarao was elevated as an archdiocese by Pope Paul VI and Domingo was appointed as the first archbishop of Tuguegarao. He is the longest serving ordinary of Tuguegarao.
