Rocaille (US: /roʊˈkaɪ, rɒˈkaɪ/ ro(h)-KY, French: [ʁɔkɑj]) was a French style of elaborate design that appeared in furniture and interior decoration during the early reign of Louis XV. A reaction against the heaviness and formality of the Louis XIV style, it featured an abundance of curves, counter-curves, undulations, and elements modeled on nature. Beginning around 1710, it reached its peak in the 1730s, and came to an end in the late 1750s when it was replaced by Neoclassicism. It marked the beginning of the French Baroque movement in furniture and design, as well as the beginning of the Rococo movement, which had spread to Italy, Bavaria, and Austria by the mid-18th century.
