The Alsószentmihály inscription is an inscription on a building stone in Mihai Viteazu, Cluj (Transylvania, present day Romania). The origins and translation of the inscription are uncertain.
The stone was an ancient Roman building stone—proved by the leaf-symbol, a frequently applied ornamental element of ancient Roman inscriptions—reused in the 10th century.
Historian Gábor Vékony has analysed the text and provided a translation, but others have criticised the theories and translation.
