Heinrich Marx (15 April 1777 – 10 May 1838) was a lawyer and the father of the revolutionary leader and influential socialist thinker Karl Marx.

However, in spite of their disagreements, Karl always retained a strong affection for his father, his daughter Eleanor writing “he never tired of talking about him, and always carried an old daguerreotype photograph of him”. On Karl's death, Engels laid the photograph in his coffin.[8]
