The House of Tatischev or Tatishchev (Russian: Тати́щевы) is a Russian noble family traditionally believed to be descended from the Princes of Solomerech of the Rostislavichi of Smolensk. This version of the Tatischev family's genealogy had made it to the Velvet Book. A cadet branch of the family bears the title of counts. The Tatischevs are listed in the Parts 5 (titled nobility) and 6 (ancient nobility) of the genealogical books of Moscow, Tver, Tula, Kostroma, Penza and Saint-Petersburg governorates. From the four lineages of the family, the cadet one was granted the title of counts in 1801.
