Mamertas Indriliūnas (28 January 1920 – 21 February 1945) was a Lithuanian writer, literary critic, translator, and anti-Soviet partisan.

In Vytautas Magnus University he studied Lithuanian language and literature and joined Vincas Mykolaitis-Putinas's Šatrija art circle, as well as the theatre seminar headed by Balys Sruoga, developing a strong friendship with Bronius Krivickas.

[1][3] He entered the Theology-philosophy faculty of Vytautas Magnus University in 1938[1][4] and chose Lithuanian language and literature as his main branches of study, with pedagogy and psychology being side-studies.

In newspapers like Ateitis and Naujoji Romuva Indriliūnas wrote about the works of poet Jonas Aistis and also the modernist tendencies of Bronius Krivickas.

[4] In his 1944 diploma work entitled V. Mykolaičio-Putino lyrikos kelias (The Lyric Path of V. Mykolaitis-Putinas), Indriliūnas characterized a poet's struggle for personality and creative freedom as a rebellion of the soul against an oppressive being.

[1] Indriliūnas also translated the works of Francis Jammes, W. B. Yeats, Rainer Maria Rilke and Oscar Milosz.
