The Last Ringbearer (Russian: Последний кольценосец, romanized: Posledniy kol’tsenosets) is a 1999 fantasy fan-fiction book by the Russian paleontologist Kirill Eskov. It is an alternative account of, and an informal sequel to, the events of J. R. R. Tolkien’s The Lord of the Rings. It has been translated into English by Yisroel Markov, but the translation has not been printed for fear of copyright action by the Tolkien Estate.

Eskov bases his novel on the premise that the Tolkien account is a “history written by the victors”. Mordor is home to an “amazing city of alchemists and poets, mechanics and astronomers, philosophers and physicians, the heart of the only civilization in Middle-earth to bet on rational knowledge and bravely pitch its barely adolescent technology against ancient magic”
