Ivica Petanjak (born 29 August 1963) is a Croatian franciscan friar who serves as a bishop of the Roman Catholic Diocese of Krk since March 22, 2015.

Petanjek took his lifetime vows on October 4, 1988, and was ordained a priest on June 24, 1990, in Zagreb Cathedral by Cardinal Franjo Kuharić.

From August 2014 until his appointment as bishop of Krk in March 2015, he served as a superior of the Capuchin monastery in Osijek and provincial definitor.

The main consecrator was Cardinal Josip Bozanić, while co-consecrators were Archbishop of Hyccarum Alessandro D'Errico, and Emeritus bishop of Krk Valter Župan.

He gave his phone number, e-mail and home address to his people, admonishing them in his homily on the day of his consecration to never forget to visit him if they are nearby, and to never hesitate to call him if they need anything.
