Piz Daint (Romansh: [pits ˈdajnt]) is a mountain of the Swiss Ortler Alps, overlooking the Ofen Pass in the canton of Graubünden.

The closest locality is Tschierv on the north side.

The name was originally spelled Piz d'Aint, which is Romansh for "inner peak".

The name was officially changed to Piz Daint towards the end of the 20th century.

Piz Daint is the namesake of the CSCS supercomputer announced in 2013.
