Rococo (less commonly roccoco) is a style of 18th century French art and interior design. Rococo rooms were designed as total works of art with elegant and ornate furniture, small sculptures, ornamental mirrors, and tapestry complementing architecture, reliefs, and wall paintings. It was largely supplanted by the Neoclassic style.

The word Rococo is seen as a combination of the French rocaille, or stone garden (referring to arranging stones in natural forms like shells), and the Italian barocco, or Baroque style. Due to Rococo love of shell-like curves and focus on decorative arts, some critics used the term to derogatively imply that the style was frivolous or merely modish; when the term was first used in English in about 1836, it was a colloquialism meaning "old-fashioned". However, since the mid 19th century, the term has been accepted by art historians. While there is still some debate about the historical significance of the style to art in general, Rococo is now widely recognized as a major period in the development of European art.
