The Moesi (Gk. Moesoi) were a Daco-Thracic tribe who inhabited part of what would become the Roman province of Moesia, which was named after them. Thracologists suggest that the Moesi may have spoken a language or dialect intermediary between Dacian and Thracian.

Of their language or dialect, only a few items are recorded; their ethnonym (Moesoi, Moesi), some toponyms and anthroponyms, and a phytonym: Mendruta, the Moesian name for the False Helleborine (L. Veratrum nigrum) or the Beet (L. Beta vulgaris).
