Stadio Artemio Franchi is a multi-purpose stadium in Siena, Italy.

In summer 2007, A.C. Siena agreed to rename the stadium 'Stadio Artemio Franchi – Montepaschi Arena', to include the name of their main sponsor, Banca Monte dei Paschi di Siena.

The new stadium, with a capacity of 20,000, features a revolutionary below-ground design which was honoured with an MIPIM AR Future Projects Award.
