The Diocese of Basel (German: Bistum Basel; Latin: Diœcesis Basileensis) is a Latin Catholic diocese in Switzerland.

Historically, the bishops of Basel were also secular rulers of the Prince-Bishopric of Basel (German: Fürstbistum Basel).

The bishop of Basel has not resided in the city of Basel since 1528. Solothurn is the seat of the Bishop of Basel.

Today the diocese of Basel includes the Swiss cantons of Aargau, Basel-Landschaft, Basel-Stadt, Bern, Jura, Lucerne, Schaffhausen, Solothurn, Thurgau, and Zug.
