Saint Anne Round Church in Kallósd, Catholic church building in Kallósd, Hungary.

The Saint Anne Round Church stands in the cemetery above Kallósd, built of brick on a stone base with a conical, bell-shaped metal roof and a small wooden tower rising from its centre. A lower horseshoe apse adjoins the east side, separated from the nave by a pointed triumphal arch. Its interior diameter is 5.8 metres, and the walls are divided outside by vertical pilaster strips.

Kallósd was a royal estate of Zalavár until the king granted it to the sons of Orosz of Komár after 1203. Their descendant Miklós, son of Karacs, built the parish church around 1260; it was recorded in 1263 as dedicated to Saint Nicholas. From the 14th century it belonged to the Abbey of Kapornak. Abandoned during the 17th-century Turkish attacks, it was cleared of thicket and rebuilt in 1740 by Abbot Imre Békási.

The church is named after Saint Anne, to whom the medieval parish church was dedicated by 1263. Its patronal feast, the búcsú, is held on 26 July. Concerts take place in July and August, and the building also appears on the village coat of arms.

The church stands in the cemetery outside the village, not in the centre, where a newer church was built beside the bell tower in the 1990s. Mass is held there regularly; in the round church only occasionally, with rare weddings. Concerts take place in July and August, and the parish feast is on 26 July.

Six identical Gothic pointed niches and a seventh, slightly smaller one are cut into the church wall. A stair on the northern wall leads up to a wooden gallery above the entrance. The interior holds no furnishings; its simple altarpiece depicts Saint Anne, the church's patron.
