Henchir-Boucha is a former Catholic diocese and archaeological site in Tunisia.^[1][2][3]

Henchir-Boucha is at 36°31′41″N 9°53′10″E^[4] between Majaz al Bab and Bir al Mashariqah, central Tunisia. The site is 189 meters above sea level.^[5] and is on the Oued Zitoun lake and Oued es Sid River.^[6]

During the Roman Empire and late antiquity Henchir-Boucha was the site of an ancient Roman town^[7] called Tubyza and was in the Roman province of Africa Proconsularis (now northern Tunisia). The remains of a large Roman Circus is at the site.^[8][9][10]

Tubyza may have been a suburb of the nearby city Municipium Aurelium Commodianum.

Tubyza was the seat of an ancient Catholic bishopric.^[1][11] It is now a titular bishopric.^[12]

In antiquity, two bishops from Henchir-Boucha are known. Felix of Tubyza, was beheaded in Rome under Diocletian (15 January 304) for not handing over scriptures (traditor),^[13][14] and Honorius, who attended the Council of Carthage (411).^[13] The current bishop is Lucio Alfert of Paraguay.
