Argedava (Argedauon, Sargedava, Sargedauon, Zargedava, Zargedauon, Ancient Greek: Αργεδαυον, Σαργεδαυον) was potentially an important Dacian town mentioned in the Decree of Dionysopolis (48 BC),[1] and maybe located at Popești, a district in the town of Mihăilești, Giurgiu County, Muntenia, Romania.

In a later section, the inscription also refers to the Dacian king Burebista and mentions that Akornion was his chief adviser (Ancient Greek: πρῶτοσφίλος, literally "first friend").

One school of thought, led by historians Constantin Daicoviciu and Hadrian Daicoviciu, assumes that the inscription talks about Argidava and place the potential capital of Burebista at Vărădia, Caraș-Severin County, Romania.

Others, led by historian Vasile Pârvan and Radu Vulpe place Argedava at Popești, Giurgiu.

Arguments include the name connection with the river Argeș, geographical position on a potential road to Dionysopolis which Akornion followed, and most importantly the size of the archaeological discovery at Popești that hints to a royal palace.
