The Twelve Months (Russian: Двенадцать месяцев; Dvenadtsat mesyatsev) is a 1956 Soviet traditionally animated feature film directed by the "patriarch of Russian animation", Ivan Ivanov-Vano. It was produced at the Soyuzmultfilm studio in Moscow and is based on the fairy-tale play of the same name by Samuil Marshak. The scene of action in the animated film isn't specified, but on a picture it is clear that action happens in the West (in the original of the story of Marshak — in Bohemia, then part of the Austrian empire) at the turn of the eighteenth to nineteenth centuries. The animated film plot quite precisely reflects story events, thus the particular emphasis is placed on ridiculing the shortcomings of an absolute monarchy.

The film's sound and image were restored in by Krupnyy Plan, who released it on video and DVD in Russia in 2005. An English-subtitled edition of the Russian-language version has not been released. However, Films by Jove released the film on DVD in 1999 as "volume 3" of its Stories from My Childhood series - this version features a choice of English, French or Spanish soundtracks.
