Samaheej (Arabic: سماهيج Samāhīj, Classical Syriac: ܡܫܡܗܝܓ Mashmahig,[1] Persian: سه ماهی Se Mahi),[2] is a village in Bahrain on the northern coast of Muharraq Island.

Samaheej was home to a historical Christian community, the remains of which have been uncovered through archaeological excavations at the site.

Among the famous people from Samaheej is Abdullah bin Saleh al Samahiji (1675 - 1722), a medieval Islamic scholar, prominent within the Akhbari school of Shiism during the Safavid era.

[2] Interestingly, Bahrain's old population is said to have had a Persian clergy (Zoroastrians) who used Syriac as a language of liturgy and writing more generally,[6] in addition to a Nestorian Christian church that was uncovered in Samaheej.

[3][4][5] In 2024, it was published that archaeologists from the University of Exeter and the Bahrain Authority for Culture and Antiquities discovered a well-constructed building likely serving as the bishop's palace, containing domestic rooms, a kitchen, and early Christian symbols, including three plaster crosses and Chi Rho graffiti.
