The Banca di Credito Sardo S.p.A. was an Italian bank headquartered in Cagliari, Sardinia.

The head office building, located in Cagliari, was designed by the Italian architect Renzo Piano.

Credito Industriale Sardo, ente di diritto pubblico con personalità giuridica propria, was established in 1953 as one of the 19 Mediocredito of Italy, as well as one of the three Istituti per il Finanziamento a Medio Terminealle Medie e Piccole Industrie nell'Italia Meridionale e Insulare (Istituti Meridionale), which were funded by Cassa per il Mezzogiorno.

Due to Legge Amato, the bank became a limited company (Italian: Società per Azioni) in 1992.

At the same time the core business (medium term lending to enterprises) was transferred to Mediocredito Italiano (ex-Mediocredito Lombardo).
