Ħalfa Rock (Maltese: Il-Ġebla tal-Ħalfa or Il-Blata tal-Ħalfa''') is a deserted small islet and limestone rock on the south-east coast of the island of Gozo in the Maltese archipelago. The islet is typified by a small maritime labiate garrigue environment, with germander and prasium shrubs, with the occurrence of the endemic Maltese Pyramidal Orchid as well as endemic coastal communities based on the Maltese Sea-Lavender and the sub-endemic Maltese Crosswort.
