The Ioachim Chronicle or Ioakim Chronicle[1] (Russian: Иоакимовская Летопись, romanized: Ioakimovskaja Letopisʹ), also spelled Joachim or Ioakim) is a chronicle allegedly discovered by the Russian Imperial historian Vasily Tatishchev in the 18th century. The alleged Ioachim Chronicle, which has never been found, is part of the "Tatishchev information" (Russian: Татищевские известия, romanized: Tatishchevskie izvestiya), which is not to be trusted until it is supported by another source.[2][3]
