Harold René Charles Marie, comte d'Aspremont Lynden (17 January 1914 - 1 April 1967) was a Belgian cabinet minister, politician of the PSC-CVP and Cavalry Lieutenant-Colonel.
He was one of the Belgian authorities involved in the kidnap and assassination of Congolese Prime Minister Patrice Lumumba.
After studying classics at the abbey school at Maredsous from 1926 to 1931, he graduated from the Catholic University of Leuven as a doctor of law.
He completed his military service as a reserve officer in the 13th Line Regiment at Namur (1936–37) before returning to Leuven to study social and political economics.
In the early 21st century, writer Ludo De Witte found documents revealing that Belgian authorities were directly involved in the murder of Prime Minister of the Democratic Republic of the Congo Patrice Lumumba.
