This is a list of ancient cities, towns, villages, and fortresses in and around Thrace and Dacia. A number of these settlements were Thracian and Dacian, but some were Celtic, Greek, Roman, Paeonian, or Persian.
A number of cities in Thrace and Dacia were built on or close to the sites of preexisting Dacian or Thracian settlements. Some settlements in this list may have a double entry, such as the Paeonian Astibo and Latin Astibus. It is believed that Thracians did not build true cities even if they were named as such; the largest Thracian settlements were large villages. The only known attempt to build a polis by the Thracians was Seuthopolis., although Strabo considered the Thracian cities with "bria" ending polises. Some of the Dacian settlements and fortresses employed the traditional Murus Dacicus construction technique.
