Hornnes Church (Norwegian: Hornnes kyrkje) is a parish church of the Church of Norway in Evje og Hornnes Municipality in Agder county, Norway. It is located in the village of Hornnes. It is one of the churches for the Evje og Hornnes parish which is part of the Otredal prosti (deanery) in the Diocese of Agder og Telemark. The white, wooden church was built in an octagonal design in 1828 by Leg Askildsen Hallingskaar, a builder from Laudal who was using plans drawn up by the architect Lars Larsen Forsæth (based on the same plans for Klæbu Church). The church seats about 300 people.
The church has changed little since the time of construction. The interior is symmetrical with the pulpit in the central axis in front of the altar, following the model of the Christiansborg Castle Church in Copenhagen.
