Claus Berg (ca. 1470 – ca. 1532) was a German sculptor and painter who is remembered for his workshop in Odense and his decorative work in Danish churches, especially altarpieces and crucifixes. His finest work, the altarpiece which now stands in Odense Cathedral, was designed at the request of Queen Christine for the Franciscan abbey church of Gråbrødre (Gråbrødre Klosterkirke) which she had chosen as the burial site for her husband King Hans and herself.
