Skudra (Old Persian: 𐎿𐎤𐎢𐎭𐎼 Skudra; Ancient Greek: Σκύδρα Skúdra) was a province (satrapy) of the Persian Achaemenid Empire in Europe between 510s BC and 479 BC. Its name is attested in Persian and Egyptian inscriptions (an Egyptian record of c. 498–497 BC, and a list on the tomb of Darius the Great at Naqsh-e Rustam, c. 486 BC.). It is believed to have comprised the lands now known as Thrace and Macedon (which would correspond to parts of the regions of present-day Northern Greece and Eastern Bulgaria).
