Qasim Khanate or Kingdom of Qasim or Khanate of Qasım (Tatar: Cyrillic Касыйм ханлыгы/Касыйм патшалыгы, Latin Qasím xanlığı/Qasím patşalığı, Arabic قاسيم حانلئعئ/قاسيم پاتسالئعئ; Russian: Касимовское ханство/Касимовское царство, Kasimovskoye khanstvo/Kasimovskoye tsarstvo) was a Tatar khanate, a vassal of Russia, which existed from 1452 until 1681 in the territory of modern Ryazan Oblast in Russia with its capital Kasimov, in the middle course of the Oka River. Its khans were the patrilineal descendants of Toqa Temür, the thirteenth son of Jochi (and thus a grandson of Genghis Khan). It was established in the lands which Grand Prince Vasily II of Moscow (reigned 1425-1462) presented in 1452 to the Kazan prince Qasim khan (d. 1469), son of the first Kazan khan Olug Moxammat.

The original populations were Finnic tribes Meshchyora and Muroma, Mordvins. The land was under Kievan Rus' and Volga Bulgaria's influence. Local tribes were tributaries of Russian dukes. Later, the area was incorporated into Vladimir-Suzdal. In 1152, duke of Vladimir Yuri Dolgoruky founded Gorodets-Meshchyorskiy. After the Mongol conquest, the territory was incorporated into the territory of the Golden Horde. Turkic settlers appeared in those areas, and most of them accepted Islam under influence from the Volga Bulgars. The semi-independent principality Mishar Yurt was founded by Hordian Mohammad Shirin beg. From 1393, the area became a part of Russia. After the battle of Suzdal in 1445, Olug Moxammad claimed to return those lands to the Tatars.
