Inalchuq (or Inalchuk) (died 1219) was governor of Otrar in the Khwarezmian Empire in the early 13th century, known mainly for helping to provoke the successful and catastrophic invasion of Khwarezmia by Genghis Khan.
Inalchuq was an uncle of Sultan Muhammad II of Khwarezmia. His name meant "little Inal" in his native Turkic, and he held the title Ghayir-Khan.[1]
