Hephæstus was a town in Roman Egypt, in the province of Augustamnica Prima, the eastern part of the Nile Delta.

The name Hephæstus is known only from ecclesiastical sources; its Egyptian name and its site are unknown.

The original diocese was in Augustamnica Prima, a suffragan of Pelusium.^[1]

It is mentioned by Hierocles^[2] and by George of Cyprus, as among the thirteen towns of Augustamnica Prima.

Le Quien^[3] mentions only two bishops: John, who took part in two Councils of Ephesus (First, 431 and Second, 449), and Peter, present at the Council of Constantinople in 459.^{[dubious – discuss]}

It remains a Roman Catholic titular see.
