Tadeusz Rechniewski (2 April 1862, Saint Petersburg – 21 July 1916, Warsaw) was a Polish revolutionary and one of the leaders of the First Proletariat party.
In 1889, Rechniewski was joined by his wife, who was helping to support political prisoners.
In 1894, he was sent to settle in the Transbaikal region, where he worked as a draftsman in the construction of the Trans-Siberian Railroad.
In 1901, he moved to Irkutsk, where he worked for the newspaper Eastern Review (Восточное обозрение).
During all this time, he continued his revolutionary activities and organized escapes for other exiles.
