The kokoshnik () is a traditional Russian headdress worn by women and girls to accompany the sarafan. The kokoshnik tradition has existed since the 10th century in the city of Veliky Novgorod. It spread primarily in the northern regions of Russia and was very popular from 16th to 19th centuries. It is still to this day an important feature of Russian dance ensembles and folk culture and inspired the Kokoshnik style of architecture.
