The Church of San Leonardo, Italian: Chiesa di San Leonardo, is a cave church in the rione of Sasso Caveoso of Matera, in Basilicata in southern Italy.
The date of foundation of the church is unknown; it was first documented in 1543–44, when it was without a door and repairs were ordered.
The interior consists of two naves divided by a massive central column of living rock.
The fresco of San Leonardo was probably situated in a small niche, decorated with shells, on the left wall; only traces remain.
