Ritona (also known as Pritona) is a Gallo-Roman Celtic goddess chiefly venerated in the land of the Treveri in what is now Germany. Her cult is attested at Pachten and at Trier, where she "had a carefully built little temple" in the Altbachtal complex. Ritona's temple was one of several in the Altbachtal to include exedrae and courtyards that may have been used to prepare ritual banquets and/or to place offerings. At Pachten her temple also had a theatre, presumably used for performances of a religious nature.

== Name == The theonym Ritona is generally interpreted as meaning 'that of the ford', stemming from the Gaulish root ritu- ('ford'; cf. Old Irish Humar-rith, Welsh rhyd 'ford'). This suggests that she was a goddess of fords; Jean-Marie Pailler remarks that, "Water crossings required religious precautions that were written into the landscape, toponymy, and ritual: Ritona is thus well at home among the 'crossers' who were the Treveri". The translation 'that of the course [of the river]' is also possible, by deriving Ritona from the homonym root ritu-, rito- ('course'; cf. Old Irish riuth, Welsh rhed 'course'), although the name Trēveri is also generally seen as meaning 'those crossing the river', that is to say the 'ferrymen'.
