Palazzo Salimbeni is a Gothic style urban palace located on the Piazza Salimbeni, just off Via Banchi di Sopra in the Terzo di Camollia of the city of Siena, region of Tuscany, Italy.
The building, associated with an ancient mercantile family of Siena, currently houses the main offices of the Banca Monte dei Paschi di Siena, the oldest bank in the world.
In the 19th century it was remodeled in neo-Gothic style, with detail including the merlons, the Lombard bands under them, the ogival triple mullioned windows, inspired by Siena's Palazzo Pubblico.
It faces a square with a statue of the local religious figure Sallustio Bandini, dating to 1882.
South along Via Banchi di Sopra are the Palaces Bichi Ruspoli ad Tolomei.
