Athanasios Christopoulos (1772–1847), Greek poet, was born at Kastoria in Macedonia.
He studied at Buda and Padua, and became tutor to the children of Alexander Mourousis, Prince of Wallachia. After the fall of that prince in 1811, Christopoulos was employed by John Caradja, who had been appointed hospodar of Walachia, in drawing up a code of laws for that country.
On the removal of Caradja, Christopoulos retired into private life and devoted himself to literature. He wrote drinking songs and love ditties which are very popular among the Greeks. He is also the author of a tragedy, of Politika Parallela (a comparison of various systems of government), of translations of Homer and Heraclitus, and of some philological works on the connection between ancient and modern Greek.
His Hellenika Archaiologemata (Athens, 1853) contains an account of his life.
