The Catacomb of Novatian is a two-level catacomb on viale Regina Elena in Rome, at the junction of piazzale San Lorenzo and via Tiburtina in the modern Tiburtino quarter.
It is not mentioned in any ancient sources and so its name (still debatd by scholars) derives from a mid 4th century inscription found there in April 1932 in a large niche with a table-form tomb, painted red and with a mosaic border.
It reads Novatiano beatissimo marturi Gaudentius diaconus fecit (Gaudentius the deacon made this [dedicated] to Novatian the most blessed martyr).
