Schrattenbachův palác, Baroque palace in Brno, Czech Republic.

Schrattenbachův palác is a Baroque palace on Kobližná Street, built around two earlier houses and given its present form by Mořic Grimm, who added the second floor in 1735–1738; a half-floor followed in 1847. Its courtyard was rebuilt in 1998–2001 with steel galleries and a glass pyramid roofing the library atrium.

Two houses bought in 1703 by Countess Marie Elisabeth Breuner were replaced by a palace designed by Christian Alexander Oedtl. In 1725 it passed to Olomouc bishop Cardinal Wolfgang Hannibal von Schrattenbach, who had Mořic Grimm rebuild it in 1735–1738, adding the second floor and giving it its present form.

The palace's name comes from Cardinal Wolfgang Hannibal von Schrattenbach, Bishop of Olomouc, who bought it in 1725 and had Mořic Grimm rebuild it between 1735 and 1738. Since 1950 it has housed the Jiří Mahen Library, whose central space is the glazed courtyard atrium built in the 1998–2001 reconstruction.

The Jiří Mahen Library has been based here since 1950, not 1951, and the building is open to the public during library hours. Enter from Kobližná Street; the general reconstruction of 1998–2001 replaced the southern wing and courtyard additions with a steel structure and glass pyramid that now forms the library's central hall.

Mozart, aged eleven, spent the Christmas holidays of 1767–1768 in the palace with his father Leopold and the family of Franz Anton von Schrattenbach, staying in Moravia during a smallpox epidemic in Vienna. A memorial plaque by Jan Fischer was placed on the facade in 1956.
