Constantine Sathas (; Athens, 1842 – Paris, 25 May 1914) was a Greek historian and researcher.
Sathas spent his life unearthing hitherto unknown material pertaining to the history of late medieval and early modern Greece that he later published. He researched archives in Greece, Constantinople (now Istanbul), Venice and Florence. In 1900, he moved to Paris, where he lived until his death.
Many of the numerous documents he brought to light still remain primary sources of information. It can be argued that his work was never fully appreciated and some of his views are regarded eccentric nowadays. Yet, he carried out groundbreaking work and has been considered as the best historian of Greece in the 19th century.
