The Gulf of Salerno is a gulf of the Tyrrhenian Sea in the coast of the province of Salerno in south-western Italy. The northern part of this coast is the touristic Costiera Amalfitana, including towns like Amalfi, Maiori, Positano and the city of Salerno itself.

The Gulf of Salerno is separated from the Gulf of Naples (on the north) by the Sorrentine Peninsula, while from the south it is bounded by the Cilento coast.
