Sculptris is a virtual sculpting software program, with a primary focus on the concept of modelling clay. It entered active development in early December 2009, and the most recent release was in 2011.

Users can pull, push, pinch, and twist virtual clay. It is geared toward character sculpting and "organic" models.

3D meshes (.obj) can be imported into the program for further detailing, generating normal and displacement maps.

In late July 2010, Sculptris inventor Tomas Pettersson joined the Pixologic team (makers of ZBrush), who have taken over Sculptris development.
