Nekrasov Cossacks, Nekrasovite Cossacks, Nekrasovites, Nekrasovtsy () are descendants of Don Cossacks which, after the defeat of the Bulavin Rebellion fled to the Kuban (in September 1708), headed by Ignat Nekrasov, hence the name. The Kuban was then under the rule of the Crimean Khanate. Later they were joined by other fugitives from the Don and runaway Russian serfs. The Nekrasovites were Old Believers, a persecuted faith.
