Gipsoteca canoviana, Art museum and plaster cast gallery in Possagno, Italy.

Gipsoteca canoviana is a museum complex in Possagno made up of Canova's birthplace, a basilica-shaped gallery built by Francesco Lazzari between 1834 and 1836, and a 1957 wing by Carlo Scarpa. The gallery's barrel-vaulted ceiling has recessed rectangular coffers, the floor is laid with red-brown and white tiles in diamonds and triangles, and white plaster statues stand on plain pedestals along both walls. Large white relief panels are set into the upper walls, and a dark opening at the far end leads into a further arched hall.

Giovanni Battista Sartori, Canova's half-brother and bishop of Mindo, had the gallery built to house the plaster models and clay sketches from the sculptor's Roman studio. The works were moved to Possagno from 1829, and the Venetian architect Francesco Lazzari built the basilica-shaped hall between 1834 and 1836. Sartori transferred the buildings and collections to the comune of Possagno in 1853.

The name gipsoteca means "collection of chalk". Canova's process moved from drawings to small clay models, then to life-size clay, from which a plaster mould was cast; only one plaster model served as the guide for the marble. The only surviving full sequence is Adonis Crowned by Venus, left unfinished for lack of payment and displayed at the entrance.

The museum is split between Canova's birthplace house and the basilica-shaped gallery beside it, with the 1957 Scarpa wing reached from the older hall. The plaster gallery ends in a dark opening onto a further arched hall of statues, so allow time to continue beyond the first room. The garden and Brolo orchard lie in front of the house.

The plaster model of Canova's George Washington stands in the gallery; the marble version, installed in the North Carolina State House rotunda in 1821, was destroyed when the building burned in 1831. The model travelled to the Frick Collection in New York for an exhibition in 2018.
