The Karakuş Tumulus is a funerary monument—a hierothesion—for Queen Isias and Princesses Antiochis and Aka I of Commagene, built by Mithridates II of Commagene in 30–20 BCE, near the modern village of Çukurtaş in Kâhta District, Adıyaman Province, Turkey.
Karakuş means "black bird". The monument received this name because there is a column topped by an eagle.
It is located 12 kilometres from Kâhta, Turkey. The tumulus is surrounded by groups of three Doric columns, each about 9 metres high. The columns are topped with steles, reliefs and statues of a bull, lion and eagle. An inscription indicates the presence of a royal tomb that housed three women.
