Strombolicchio is a sea stack of volcanic origin 2 km (1.2 mi) to the northeast of the island of Stromboli in the Aeolian Islands of Italy.

Geologically, Strombolicchio is a volcanic plug or spine of extremely hard compacted basalt resistant to erosion, and is the remnant of the original volcano from which the island of Stromboli was built up, whose eruptions ceased approximately 200,000 years ago, since when the volcanic activity has moved about 3 km (1.9 mi) to the southwest. It is the only subaerial part of a submarine platform that extends between it and the main island.

A lighthouse is located on its summit, reached by a concrete staircase of over 200 steps. The island is a tourist attraction in Stromboli.

Its name in the Sicilian language means Little Stromboli.
