Reitia (Venetic: 𐌓𐌄:𐌉:𐌕𐌉:𐌀) is a goddess, one of the best known deities of the Adriatic Veneti of northeastern Italy.

While her place in the Venetic pantheon cannot be known for certain, the importance of her cult to Venetic society is well attested in archaeological finds. A large body of votive offerings on pottery and metal objects has been found at a Venetic shrine in Baratella, near Este. In Venetic, she is given the epithets Śahnate, the Healer, and Pora, the good and kind.

She was also a deity of writing; Marcel Detienne interprets the name Reitia as "the one who writes" (compare Proto-Germanic *wreitan- 'to write'). Inscriptions dedicating offerings to Reitia are one of our chief sources of knowledge of the Venetic language.^[1] The Romans identified her with Diana also under greek name Artemis. the Roman era inscriptions from Northern Italy and the Alpine region show Diana and the Greek Artemis taking Reitia's place as healer, a function only oberved in that area, like the roll-up silver sheet found in Austria, though incomplete it reads: "For migraines. Antaura came out of the ocean; she cried like a deer; she moaned like a cow. Artemis Ephesia met her: 'Antaura, where are you bringing the headache? Not to the . . .” this inscription is dated to the 2nd century A.D. On the other hand, Strabo tells how the people of Northern Italy worshipped Artemis above all other gods, hinting at her syncretism to the local Raetia.
