Ivan Kozarac (February 8, 1885 – November 16, 1910) was a Croatian novelist, poet and writer of short stories.
As a thirteen-year-old boy wanting to avoid the family poverty, he was employed as a clerical trainee in a district in Vinkovci.
In 1909, he returned to his hometown, but in the fall of the year he went to Zagreb where he was employed as a fund manager and director of the Croatian Writers Society.
He was a narrator of the life of typical villages of Šokadija during a time when the Military Frontier was freshly reintegrated into Slavonia.
He wrote much about the corruption of women and fashion and took a critical stance towards the Church, the wealthy life of some priests, and the false love towards God.
