Noacksches Haus, Historic residential building in Potsdam, Germany.

Noacksches Haus is a three-storey baroque town house on the Alten Markt in Potsdam, rebuilt in 2013–2016 with a facade reconstructed after the 1777 design by Carl von Gontard. A narrow balcony on six Tuscan columns spans the ground floor; above it, the first-floor windows have segmental pediments filled with shell ornaments, and six statues stand on a balustraded attic.

Originally constructed in 1777 by architect Carl von Gontard under commission from Frederick the Great, the building was destroyed during Allied bombing raids in 1945 and faithfully reconstructed between 2013 and 2016.

The house takes its name from its first owner, the innkeeper Noack, and was long known as the Noackscher Gasthof. Its facade borrows motifs from Palladio's Palazzo Chiericati in Vicenza, though the sources note that the king's models are not documented for this house; Astrid Fick links the Tuscan columns, the balcony balustrade and the window frames to that palace. Unlike the Vicenza original, the Potsdam ground floor has a balcony, a middle window with herms and rustication.

Located at Humboldtstraße 4 near the Old Market, the reconstructed building currently houses commercial spaces on the ground floor and residential apartments in the upper levels.

The building is also known as the Palazzo Chiericati because its columns, balustrades and decorative figures are strongly inspired by Palladio's Palazzo Chiericati in Vicenza. Unlike the Vicentine original, the Potsdam facade has a six-column Tuscan balcony and a middle window with herms.
