Teressa (Teressa language: Luroo, , also called Tarasa Dwip) is one of the Nicobar Islands, India.
When Austria claimed the Nicobar Islands as a colony (1778-1784) on the assumption that Denmark had abandoned its claim (1754/56-1868), they named Teressa after the Austrian Archduchess Maria Theresia. Austria abandoned its earlier claim in 1784.
