Valbygård is a manor house and estate located four kilometres northwest of Slagelse, Denmark. Created by Joachim Castenschiold in 1874 from land that had previously belonged to Antvorskov Abbey, the estate was in 1846 acquired by August Willads Bech and has since then remained in the Bech family. The current, Renaissance Revival style main building was built for August Willads Bech in 1855. It was listed on the Danish registry of protected buildings and places in 1996. The estate covers 1,100 hectares of land.
