An imaginary conceptual sculpture is a work of art that exists solely in the mind of its creator and may be interpreted by the viewer in a variety of ways. This type of sculpture often challenges traditional notions of form, material, and composition, and may incorporate abstract concepts or ideas rather than representational elements.

It may be a large-scale installation piece or a small-scale maquette made out of unconventional materials. It may also have an interactive element, inviting viewers to engage with, respond to, or even modify the sculpture in some way.

An imaginary conceptual sculpture can express political, social or environmental issues, conveying strong messages while reflecting the creativity of the sculptor. It can be a medium to represent the artists' views and perspective, allowing audiences to immerse themselves into a new kind of art that both inspires and provokes deep thought.
