The Roman Catholic Diocese of Faisalabad (Lat: Dioecesis Faisalabadensis) is a diocese of the Latin Church of the Roman Catholic Church in Pakistan.

Erected in 1960, as the Diocese of Lyallpur, the diocese was created from the Diocese of Multan. The new diocese comprised the civil districts of Faisalabad (formerly Lyallpur), Sahiwal and Jhang.

In 1977, the name of the diocese was changed to the Diocese of Faisalabad. The diocese is a suffragan of the Archdiocese of Lahore. The Diocese of Faisalabad now comprises the following civil boundaries: the whole of the Faisalabad Division with the districts of Faisalahad, Jhang, Toba Tek Singh and Chiniot.

The Focolare Movement was introduced into Pakistan in 1968 via the Faisalabad diocese by Father Juliano Ricchiardi, an Italian priest serving at the National Catechists' Training Centre in Khushpur. As of 2008, according to local sources, the movement in Pakistan counted 18 Focolarinas, 11 Focolarinos and about 400 other affiliated members including lay people, nuns and priests.
