Plastic arts are art forms which involve physical manipulation of a plastic medium by moulding or modeling such as sculpture or ceramics. The term has also been applied more broadly to all the visual arts.

Materials that can be carved or shaped, such as stone or wood, concrete or steel, have also been included in the narrower definition, since, with appropriate tools, such materials are also capable of modulation. This use of the term "plastic" in the arts should not be confused with Piet Mondrian's use, nor with the movement he termed, in French and English, "Neoplasticism."
