The name of Laveno comes from two denominations: the first is from the Latin word "labes", that means "landslide"; the second denominations is from the Roman general Titus Labienus, that give his name to the port (Portus Labienus) and subsequently to the surrounding area. The radix of the name are actually just in the main road of the town, via Labiena. Titus Labienus is considered responsible for naming Mombello too, after a battle against the Gauls ("mons belli" means "war hill").
