Ante Kovačić (June 6, 1854 - March 10, 1889) was a Croatian writer.
Born to a family of Croatian peasants, Kovačić made his way through law school to become an attorney.
He began to write in 1875. While his early works have Romantic tendencies, in later years he was influenced by Realist literature. His stories and novels often had strong satiric overtones and represent harsh criticism to injustice in Croatian society of his time. One of his novels, Među žabari, remained unfinished because citizens of Karlovac, protested after reading its first paragraphs in a local newspaper.
The best known work of Ante Kovačić is semi-autobiographic novel U registraturi (1888). In it he expressed great deal of sympathy for common Croatian people, most notably peasants whom he saw as superior to snobbish citizenry.
Kovačić was known as staunch supporter of Ante Starčević and his Croatian Party of Rights. As such he was bitterly opposed to ban Ivan Mažuranić and wrote literal travesty of Mažuranić's poem Death of Smail-Aga Čengić.
In his later years, Kovačić began to show symptoms of mental illness which gradually affected his work, including the last chapters of U registraturi.
U registraturi, combining biting social satire, naturalist descriptions of Croatian bureaucracy and peasantry, as well as fascination with the supernatural inherited from Romanticism, nevertheless remained the most powerful 19th century Croatian novel and one of the most enduring novels in Croatian history. In 1976 it was adapted into popular television mini-series starring Rade Šerbedžija.
