The Semper Gallery or Semper Building in Dresden, Germany, was designed by the architect Gottfried Semper and constructed from 1847 until 1854.
The long-stretched building in Neoclassical style closes the Zwinger courtyard on its northern side. It faces the Zwinger to the south; to the north it borders on the Theatre Square with the Semper Opera House as well as Dresden Castle and the Catholic Church of the Royal Court.
The Semper Gallery houses the Old Masters Picture Gallery.
