* Egyptian: This was her native tongue, the language of her people.
* Greek: The language of the ruling class in Ptolemaic Egypt, and the lingua franca of the Mediterranean world at the time. Cleopatra was known to be fluent in Greek, and she even wrote poetry in the language.
* Possibly Demotic: Though there is no definitive proof, it's possible that Cleopatra was also fluent in Demotic, a cursive form of ancient Egyptian used for everyday purposes.
It's worth noting that there's no historical record of Cleopatra speaking any other languages, but she was certainly exposed to others due to the cosmopolitan nature of her court.
