Georg Gatt (1843–1924) was a Tyrolean Roman Catholic priest and missionary, best known for establishing a parish and several institutions in Gaza, and his association with the Austrian Pilgrim Hospice to the Holy Family in Jerusalem, during the late 19th century.
He was appointed Vice-Rector of the Austrian Hospice in Jerusalem in 1871 by Joseph Othmar von Rauscher.
In 1879 Gatt moved to Gaza City, where he founded the Catholic parish "Zur Heiligen Familie" in 1887, focusing on pastoral care rather than proselytizing.
Following a fundraising journey back to Austria, he purchased land in Gaza, where he built a large house, established a school, and endowed a chapel.
He became a partner in two grain-steam mills located in Gaza and Ashdod, using the profits to support the local Austrian community and fund his ongoing work.
