Matryoshka dolls, also known as stacking dolls, nesting dolls, Russian tea dolls, or Russian dolls, are a set of wooden dolls of decreasing size placed one inside another. The name matryoshka, literally 'little matron', is a diminutive form of Matryosha (Матрёша), in turn a diminutive of the Russian female first name Matryona (Матрёна).
