The Cossack uprisings were a series of military conflicts between the cossacks and the states claiming dominion over the territories the Cossacks lived in, namely the Polish–Lithuanian Commonwealth and Russian Empire during the 16th, 17th, and 18th centuries. Both states tried to exert control over the independent-minded Cossacks. While the early uprisings were against the Commonwealth, as the Russian Empire gained increasing and then total control over the Ruthenian (Ukrainian) lands where the Cossacks lived, the target of Cossacks uprisings changed as well.

The Bulavin Rebellion (Astrakhan Revolt) is the name given to a war which took place in the years 1707 and 1708 between the Don Cossacks and the Tsardom of Russia,. Kondraty Bulavin, a democratically elected Ataman of the Don Cossacks, led the Cossack rebels. The conflict was triggered by a number of underlying tensions between the Moscow government under Peter I of Russia, the Cossacks, and Russian peasants fleeing from serfdom in Russia to gain freedom in the autonomous Don area. It started with the 1707 assassination of Prince Yury Vladimirovich Dolgorukov, the leader of Imperial army's punitive expedition to the Don area, by Don Cossacks under Bulavin's command. The end of the rebellion came with Bulavin's death in 1708.

In a stricter sense, the term refers to the Swedish invasion and occupation of the Commonwealth as a theatre of the Second Northern War (1655–1660) only; in Poland and Lithuania this period is called the Swedish Deluge, or less commonly the Russo–Swedish Deluge due to the simultaneous Russo-Polish War. The term "deluge" was popularized by Henryk Sienkiewicz in his novel The Deluge (1886).

Koliivshchyna was a major haidamaka rebellion that broke out in the Right-bank Ukraine in June 1768, caused by the money sent by Russia to Ukraine to pay for the fight of the locals against the Bar Confederation, the dissatisfaction of the peasants with the treatment of Eastern Catholics and Orthodox Christians by the Bar Confederation and by the threat of serfdom, the anti-nobility and anti-Polish moods among the Cossacks and peasants. The uprising was accompanied by violence against the members and supporters of the Bar Confederation, Poles, Jews and Roman Catholics and especially Uniate clergymen, culminating in the massacre of Uman.
