Antonio Abondio (1538–1591) was an Italian sculptor, best known as a medallist and as the pioneer of the coloured wax relief portrait miniature.
Born in Riva del Garda, he was trained by Leone Leoni and worked in Italy between 1552 and 1565.
His son Alessandro followed in his father's footsteps, also specializing in mythological and portrait reliefs, and marrying the widow of another court artist, Hans von Aachen.
Thirteen of Abondio's wax portraits survive, usually made on a round black slate base, decorated with tiny pearls and precious stones.
Initially his style in metal followed that of Leone Leoni, for the facade of whose house in Milan (Casa degli Omenoni) he carved eight large atlantes in stone, but later included many other influences.
