Cominotto (Kemmunett), sometimes referred to as Cominetto is an uninhabited Mediterranean island off the northern coast of Malta. Measuring only 0.25 km² in area, Cominotto lies 100 meters to the north west of Comino.
Between Comino and Cominotto lie the transparent, cyan waters of the Blue Lagoon (Maltese: Bejn il-Kmiemen, literally "Between the Cominos"). Frequented by large numbers of tourists and tour boats daily, the Blue Lagoon is a much photographed, picturesque bay, with a brilliant white, sandy base, and a rich marine life that make it popular with divers, snorkelers and swimmers. Other beaches on Comino include St. Mary Bay (Maltese: Ramla ta' Santa Marija) and St. Nicholas Bay (Maltese: Bajja San Niklaw).
