Count Guglielmo Lochis (1789 – 25 July 1859) was an Italian nobleman, politician, art collector and art connoisseur.
Born in Mozzo into a family which had been active in Bergamo since the 16th century and which had held the title of count since the 18th century,[1] he entered public life in 1816 as a member of the Lombard-Venetian guard during the visit to Bergamo of Francis II, Holy Roman Emperor. In 1835 Bergamo's Accademia Carrara made him its auction commissioner; he also served as the city's podestà from 1842 to 1848, with his resignation from the latter role triggered by the Revolutions of 1848. He died in Bergamo.
