Our Lady of Fatima Church is a place of worship for Catholic Christians in Krishnagiri, Tamil Nadu, India. This church also served as parish church for Krishnagiri. This was built around 1972 due to the insufficient space of the existing Ignatius Church which is located in Oldpet, Krishnagiri. The Fatima Mary statue which is placed inside the church was made and blessed from Fátima, Portugal. Ever year on the second Sunday of July the church celebrates a feast day which is very famous in the town. This church serves under Dharmapuri Diocese. Tamil is the language used as the medium of communication.

During the 18th century Krishnagiri Oldpet area was called Pharamahal, which means place of 12 forts. By 1786 British conquered this Paraamahal from Tippu Sultan, this made Catholic from Elathagiri and Veppanahalli settled in Krishnagiri. With the help of British soldiers, a small chapel was built, named after Loyola Ignatius. During that time, Piarists congregation took care of all the church services in Southern India so, this church also come under Piarists priest service.
