Melkite Catholic Archeparchy of Tyre, Melkite Greek Catholic archeparchy in Tyre, Lebanon

The Melkite Greek Catholic Archeparchy of Tyre is a metropolitan see covering about 1,500 km² in southwestern Lebanon, with its seat at Saint Thomas Cathedral in Tyre. The cathedral, built in 1752, has a facade of Gothic arches and stands next to the archeparchy offices and the archeparch's residence. Excavations beneath it revealed remains of a 12th-century church, preserved in place.

The see traces its origin to the church of Tyre visited by Paul the Apostle (Acts 21:3–7). A Latin archdiocese erected around 1124 became titular after the Mamluk conquest of 1291. In 1683 Archbishop Euthymios Saifi worked for communion with Rome; his nephew Seraphim Tanas became Patriarch Cyril VI in 1724. Tyre ceded territory to Sidon in 1752 and to Akka in 1759.

The archeparchy's name refers to the Melkite Greek Catholic Church, in communion with Rome since 1724. Its seat, the Cathedral of Saint Thomas, was built in 1752 with a facade of Gothic arches. In Yaroun, Melkite nuns of the Sœurs Basiliennes Salvatoriennes run a primary school and a health centre with the Order of Malta; in Tebnine, Choueirite Basilian nuns have run a school since 1995, expanded to secondary level after 2006.

The cathedral stands in the city of Tyre beside the archeparchy offices and the archeparch's residence, so the seat is found together with the administrative buildings. The territory it serves covers about 1,500 km2 across the Tyre district and neighbouring areas of Nabatieh Governorate, with parishes such as Saint-Georges in Tebnine and Saint-Élie in Aïn Ebel. Travel between these villages requires a car.

Beneath the foundations of the current cathedral lie the remains of an even older church from the 1100s that was uncovered during archaeological work. These layers show how sacred places in this region were rebuilt at the same spot across centuries.
