Acropora aspera is a species of staghorn coral in the family Acroporidae. It is found on reef flats and in lagoons in very shallow water in the western Indo-Pacific Ocean.

Description Acropora aspera is a scantily branching, colonial coral forming low clumps. The individual branches are slender and only taper towards the tips. The corallites, the little stony cups from which the polyps grow, vary in size and are crowded closely together. The lower lip of each corallite protrudes slightly. Acropora aspera varies in colour, being pale green, grey or brown, or occasionally pale blue.

Distribution and habitat Acropora aspera is found in the Indian Ocean and western parts of the Pacific Ocean. It inhabits reef flats and lagoons and grows in water up to 5 metres (16 ft) deep. Where coral zoning occurs, it is found between the shallow water Acropora pulchra, which it closely resembles, and the deeper water Acropora millepora.
