Lonate Ceppino is a comune (municipality) in the Province of Varese in the Italian region Lombardy, located about 35 kilometres (22 mi) northwest of Milan and about 13 kilometres (8 mi) south of Varese.
The name of the town has Celtic origins. The word Lonate seems to derive from the Celtic word Lona, which means water puddle. The name's origin is also confirmed by the presence of a water spring, which is located near the old church. In ancient times, this water spring was believed to be miraculous.
