The Great Turkish Invasion, also translated as the Great Turkish Troubles is the term by which the Georgian historiography refers to continuous attacks and settlement of the Seljuq-led Turkic tribes in the Georgian lands during the reign of George II in the 1080s.

The term has it origin in the 12th-century Georgian chronicle and is accepted in the modern scholarship of Georgia.

The Seljuq invasions result in a severe crisis in the kingdom of Georgia, leaving several of its provinces depopulated and weakening the royal authority, until the tide is reversed by the military victories of King David IV of Georgia (r. 1089–1125)
