The Palazzo Contarini del Bovolo (also called Palazzo Contarini Minelli dal Bovolo) is a small palace in Venice, Italy, best known for the external spiral staircase, with a plethora of arches, known as the Scala Contarini del Bovolo (of the snail).

The palace is located in a less-traveled side-street near the Campo Manin, near the Rialto. The staircase leads to an arcade, providing a charming panoramic view over some of the roof-tops of the city.
