HD星表（The Henry Draper Catalogue，缩写为HD，亨利·德雷伯星表）是哈佛大学天文台编纂的世界上第一个收录恒星光谱的大型星表，首版在1918年至1924年间出版，它给出了225,300颗恒星的光谱分类，涵盖了全天最暗达到照相星等为9等的恒星（大部分是北天的恒星），历元为1900.0。最初的HD星表包含的星主要是亮于9等的星，随后的增版增加了在某些天区的暗星。 。HD星表的构建对恒星光谱分类起先锋作用，它的星名广泛应用于辨别恒星。

这项计划最初是由哈佛天文台台长爱德华·皮克林发起的，1919年皮克林去世后，女天文学家安妮·坎农、弗莱明夫人等人继续主持编纂工作。由于美国天文学家亨利·德雷伯的遗孀资助了这个计划，因此命名为亨利·德雷伯星表。该星表出版以后，将恒星分为O、B、A、F、G、K、M等类型的分类法被天文学界广泛接受，称为“哈佛分类法”。

The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts, which gave classifications for 86,933 more stars. In all, 359,083 stars were classified. The original HD catalogue covers the entire sky almost completely down to an apparent photographic magnitude of about 9; the extensions added fainter stars in certain areas of the sky. The construction of the Henry Draper Catalogue was part of a pioneering effort to classify stellar spectra, and its catalogue numbers are commonly used as a way of identifying stars.
