The surname Mondino is among the most representative of certain areas of northern Italy, which testifies to its antiquity and local rootedness. From the etymological point of view, a traditional interpretation derives it from Mondo, held to be a Piedmontese diminutive of Edmondo. However, this hypothesis presents difficulties, since the historical documented forms —such as Mondinus in the year 1314— are earlier than the diffusion of the name Edmondo, which would be of later, literary introduction.

The name Edmondo, indeed, is an adaptation of the Anglo-Saxon Eadmund, compounded of ead ("wealth, property") and mund ("protection, defence"), and its popularity is linked in large part to the cultural diffusion of literary figures such as the character Edmond Dantès of Alexandre Dumas's The Count of Monte Cristo.

For this reason, it is more plausible to consider that Mondino does not derive directly from Edmondo, but from an older root linked to names formed with the Germanic element -mund. In this sense, the surname finds correspondences in French forms such as Mondin, Mondon, Mondet or Mondot, which likewise originate in the abbreviation of personal names with that same final element.
