Pactya or Paktye (Ancient Greek: Πακτύη) was an ancient Greek[1] city located in ancient Thrace, on the Thracian Chersonesus. It is cited in the Periplus of Pseudo-Scylax, in its recitation of the towns of the Thracian Chersonesus, along with Aegospotami, Cressa, Crithote and then Pactya, situated 36 stadia from Cardia.[2][3][4] It is said that Miltiades founded it.[5] Strabo places it on the Propontis between Crithote and Macron Teichos.[6] According to Herodotus, Miltiades the Elder ordered a wall built between Cardia, which was on the coast of Gulf of Melas and Pactya, which was on the Propontis side, to prevent invasion of the Chersonesus by the Apsinthii.[7] Alcibiades retired here the Athenians had for the second time deprived him of the command.[8] It was a member of the Delian League.[9] Pliny the Elder points out that both Cardia and Pactya later joined to form Lysimachia.[10]
Its site is located 2 miles (3.2 km) south of Bolayır, Turkey.[11][12]
