Yeruslan Lazarevich (Cyrillic: Еруслан Лазаревич), also known as Eruslan Lazarevich or, in the Tatar original, Uruslan, is the Russian folk-literature hero of The Tale of Eruslane Lazarevic, which recounts the many military and amorous adventures of a young and beautiful hero. Old Russian readers greatly enjoyed the tale; due to the variety of its content and by appearing frequently in lubok illustrated prints, it spread widely among the people. Its influence is noticeable even on some retelling of tales about Ilya of Murom.
Erusulan, Uruslan and the German form Jeruslan Lasarewitch are some of the variant spellings.
