Du Rietz (pronunciation: [’dʏrjeː]) is a Swedish noble family of French Flanders origin.
The family first came to Sweden in 1642 with Grégoire François Du Rietz (1607-1682), a French court physician in the employ of Christina, Queen of Sweden.
Grégoire François Du Rietz’ great-grandson, Lieutenant general and County Governor Anders Rudolf du Rietz (1720-1792), was raised to baronial rank in 1778 and was introduced in 1779 under the name of Du Rietz af Hedensberg, family number 299.
However, that branch of the family became extinct in 1797, with the death of one of his sons.
