"Iskra" (the Spark) was a political newspaper of Russian socialist emigrants established as the official organ of the Russian Social Democratic Labour Party (RSDLP). Its motto was "From a spark a fire will flare up".

Because of political repression under Tsar Nicholas II, "Iskra" had to be published in exile and smuggled into Russia. The newspaper was originally managed by Vladimir Ilyich Lenin, and it moved as he moved. The first edition was published in Leipzig, Germany, in December1900. Other editions were published in Munich (1900–1902) and Geneva from 1903. When Lenin was in London (1902–1903) the newspaper was edited from a small office at 37a Clerkenwell Green, EC1.

In a short time, "Iskra" became the most successful underground Russian newspaper in half a century. Lenin left the paper in 1903, following the split of the RSDLP. It ceased publication in 1905.
