Ivan Ivanovych Iskra (Ukrainian: Іван Іванович Іскра) (died July, 14, 1708) was a renegade colonel of Poltava regiment of Ukrainian cossacks (1696–1703).
Iskra belonged to the anti-Hetmanate coalition led by Vasily Kochubey.
In late 1707, Kochubey and Iskra delivered a denunciation letter to the Tsar's court that accused Ivan Mazepa of initiating talks with Stanislaus Leszczynski of Poland and Charles XII of Sweden.
Later, when the Tsar realized that they were correct, they were reburied near the Refectory Church in Kiev Pechersk Monastery.
