Aka II of Commagene, also known as Aka II () was a Princess from the Kingdom of Commagene, who lived between the 1st century BC and 1st century. She was of Armenian and Greek descent.

There are two possibilities on the origins of Aka II. She could have been the daughter of Prince Antiochus II of Commagene, who was the second son to King Antiochus I Theos of Commagene and Queen Isias Philostorgos of Commagene. The second possibility she could have been the daughter of Aka I of Commagene. Aka I was the daughter of Princess Antiochis of Commagene. Antiochis, who was the second daughter to King Antiochus I Theos of Commagene and Queen Isias Philostorgos of Commagene, thus was a sister to Antiochus II. Although Aka II was a direct descendant of Antiochus I Theos and Isias, she was either a granddaughter or great granddaughter to them.

Aka married an Egyptian Greek called Thrasyllus of Mendes who originally came from a Greek family in Mendes, Egypt. Thrasyllus was an Alexandrian grammarian, editor of Plato and Democritus, however was most noted as an astrologer. Thrasyllus became a friend to the future Roman Emperor Tiberius and through Tiberius influence, Thrasyllus and Aka II received Roman citizenship.

Aka II bore Thrasyllus two children who were:

• A son, Tiberius Claudius Balbilus. Through Balbilus they would become the paternal grandparents to Claudia Capitolina, who was the daughter of Balbilus. Capitolina would marry the Greek Prince from the Kingdom of Commagene called Gaius Julius Archelaus Antiochus Epiphanes. Through Capitolina, Aka II and Thrasyllus would become the great, grandparents of Capitolina s children with Epiphanes who were: prince Gaius Julius Antiochus Epiphanes Philopappos and princess Julia Balbilla.
• A daughter Eunia, who married the Praetorian prefect Naevius Sutorius Macro.
