Antun Mihanović (Zagreb, 10th June 1796 - Novi dvori near Klanjec, 14th November 1861), Croatian writer and lawyer.

Antun Mihanović was born in 1796 in Zagreb. He was born in a family of Zagreb landlord Matija Mihanović and Justina born Kušević. He finished elementary school and gymnasium in Zagreb. He studied philosophy and law at the Royal Academy of sciences in Zagreb. He worked as a lawyer in 1813 at Tabula Banalis (former Supreme Court) in Zagreb, and from 1815 to 1821 he was a military judge, mainly in Italy, after that he worked as an administrative officer in Rijeka from 1823 – 1836. In 1827 he was representative of Rijeka on Požun parliament, and in Rijeka he wrote the lyrics of the poem Horvatska domovina (Our Beautiful Homeland). After that he moved to Austrian diplomacy and was there in the service from 1836 – 1858. He was the first Austrian consul in Belgrade, and afterwards in Salonika, Smyrna, Istanbul and Bucharest. He retired in 1858 as a minster adviser, and from then until his death he lived in Novi Dvori.

Mihanović earned his eternal fame by the poem Horvatska domovina that at the end of 19th century became Croatian national anthem. The poem was first published in the tenth issue of Gaj’s Danica, on the 14th March 1835. In it, the poet gathered all that cannot be tear off from us as long as we live as a nation, which will always revive us and wake our patriotic feelings (Antun Barac). For Horvatska domovina (Croatian homeland) or, according to the first verse, Our Beautiful the first motif was translated in the melody, according to the general opinion, by Josip Runjanin from Vinkovci, and the music was composed, according to the word of mouth, which is very probable, by Vatroslav Lichtenegger, singing teacher and organist of the cathedral in Zagreb. It was performed for the first time in public in 1861. As the national anthem it was adopted in 1891.
