The Chiesa di San Pietro is a church located in the town of Porto Venere, in the Italian region of Liguria. It is situated on a promontory overlooking the sea and is one of the most iconic landmarks of the town.

The church was built in the Gothic style in the 13th century and has undergone several modifications over the centuries. Its façade is characterized by a large rose window and a pointed arch portal. The interior is divided into three naves with a vaulted ceiling and is decorated with frescoes dating from the 14th and 15th centuries.

The most striking feature of the Chiesa di San Pietro is its position, perched on a rocky outcrop that rises out of the sea. The church is accessed by climbing a steep flight of steps that offer panoramic views of the town and the sea.
