Giocondo Albertolli (24 July 1742 – 15 November 1839)[1] was a Swiss-born architect, painter, and sculptor who was active in Italy during the Neoclassical period.

Albertolli was born into a family of artists in Bedano, a village 7 km north of the (at the time) landvogtei capital Lugano in what today is Ticino.

In 1774, he returned to his family in Bedano; soon he met up with Giuseppe Piermarini for whom he collaborated in future stucco decoration of palaces in Milan.

In 1776 Albertolli was nominated Professor of ornamenti architettonici (architectural ornament) at the newly created Brera Academy in Milan; he held this post for more than a quarter of a century until failing eyesight caused him to resign in 1812.

Giocondo's nephew, Giacomo Albertolli, was a professor of civil architecture in Padua and later in Milan, where he replaced his former teacher, Piermarini.
