Dalby Church (Swedish: Dalby kyrka), sometimes also called the Church of the Holy Cross in Dalby (Helgakorskyrkan i Dalby) is a church in Dalby, Lund Municipality in the Swedish province of Scania. It is one of the oldest churches in Sweden. When it was built Dalby was part of Denmark, and the church was commissioned by King Sweyn II of Denmark. It was constructed during the second half of the 11th century. For six years, it served as the seat of a bishop, before the diocese was merged with the Diocese of Lund nearby. The church was built with inspiration from Hildesheim Cathedral, and masons from Hildesheim appear to have worked on its construction site.
