Cominotto (Maltese: Kemmunett), sometimes referred to as Cominetto, is an uninhabited Mediterranean island off the northwestern coast of Comino, itself located between the two main Maltese islands of Gozo and Malta. It is located just off the eponymous larger island of Comino and is part of the Maltese archipelago. Measuring 0.25 square kilometres (0.10 sq mi) in area, it is the largest uninhabited island in Malta.

The island has a rugged coastline and rocky terrain. It is home to several species of seabirds and predatory rats. Adjacent to Cominotto lies the Blue Lagoon, a popular destination for tourists in the Maltese archipelago. Due to its ecological importance, Cominotto is part of a Special Protection Area.

Cominotto was used by the Romans as a hunting ground. In more recent centuries, the island has been uninhabited.^{[citation needed]}
