Ivan Mykolaiovych Vahylevych (Ukrainian: Іван Миколайович Вагилевич; born 2 September 1811 in Yasen, today in Kingdom of Galicia and Lodomeria, Austrian Empire – died 10 May 1866 in Lviv, Kingdom of Galicia and Lodomeria) was a Ukrainian Romantic poet, philologist, and ethnographer of the Galician revival in Western Ukraine.

Vahylevych neglected his studies at the university frequently in order to make field trips to villages in western Ukraine, where he conducted archeological and ethnographic fieldwork.

[1] Because of his populist activities, cultural nationalist views, and correspondence with scholars in the Russian Empire, namely Mikhail Pogodin, Izmail Sreznevsky, and the Ukrainians Mykhailo Maksymovych and Osyp Bodiansky, he suffered harassment by the church and Austrian civil authorities.

Being a democratic Polish-Ukrainian political federation sympathizer, he took up the editorship of Dnewnyk Ruskij, the weekly run by the Ruthenian Congress.

Ostracized by Catholic Ukrainians and by the Hierarchy of the Church, he was unable to find steady work until 1862, when he was appointed to the city archives in Lviv.
