Following the unification of Italy, in 1861, a reorganization of the internal subdivisions of the country ensued. By decree of March 17, 1869, the comuni of Paderno, Dugnano, Incirano, Cassina Amata and Palazzolo Milanese were fused into a new comune called Paderno Milanese.

Other names for the comune were proposed (including Padergnano and Borgosole) through the 1880s.
By decree of February 1, 1886, the comune's name was formally changed to the current name of Paderno Dugnano.

Paderno received the honorary title of city with a presidential decree on September 25, 1989.
