The Yukjin dialect (Yukjin Korean: 육진말; Hanja: 六鎮말; RR: Yukjinmal) is a variety of Korean or a separate Koreanic language spoken in the historic Yukjin region of northeastern Korea, south of the Tumen River. Its phonology and lexicon are unusually conservative, preserving many Middle Korean forms. Thus, Alexander Vovin classified it as a distinct language.
Yukjin speakers currently live not only in the Tumen River homeland, now part of North Korea, but also in the Korean diaspora in Northeast China and Central Asia that formed in the nineteenth and twentieth centuries. The dialect is under pressure from the Gyeonggi ("Seoul") dialect, the prestige dialect, as well as local Chinese and Central Asian languages.
