Studio Wall (1872) is an oil painting by the German artist Adolph Menzel, now in the collection of the Hamburger Kunsthalle. It is considered one of the "masterpieces of Menzel's maturity", and the artist deemed it his best painting. Studio Wall was preceded by a work of the same title painted in 1852, an oil on paper now in the Alte Nationalgalerie in Berlin. That painting features casts of two arms and a separate hand, the arms arranged so as to suggest a relationship to a body from which they have been removed.
