Antonio Missaglia (1416/17–1495/96) was an Italian armourer.
Missaglia's last name was a nickname taken by the artist based on where he was born (Missaglia). The original family name was Negroni.[1] Both Antonio and his brother Tommaso created armor by trade, primarily to nobles and knights in Milan. Some of Missaglia's pieces can be seen at the Kunsthistorisches Museum.
