Casa Scaccabarozzi, commonly known as Fetta di Polenta (Fëtta 'd Polenta in Piedmontese, meaning "slice of polenta"), is a historic building located in the Vanchiglia neighborhood of the northern Italian city of Turin. It is famous for its unusual and very thin trapezoidal plan and for being only 54 centimetres (1.77 ft) at its narrowest. Its primary nickname due to its resemblance to the shape to a slice of polenta.

It was designed by famous architect Alessandro Antonelli, and its name derives from the surname of the architect's wife, Francesca Scaccabarozzi, a noblewoman from Cremona. The couple lived in the building for only a few years, and then moved to the adjacent building, also designed by Antonelli.
