Hacı I Giray (1397–1466, ruled circa 1441–1466) was the founder of the Crimean Khanate and the Giray dynasty of Crimea. As the Golden Horde was breaking up, he established himself in Crimea and spent most of his life fighting off other warlords. He was usually allied with the Lithuanians. His name has many spellings, such as Haji-Girei and Melek Haji Girai (; , ).
