Johannes Dam Hage (2 April 1800 – 16 September 1837) was founder and editor-in-chief of the Danish republican journal Fædrelandet which had a decisive influence on the establishment in Denmark of a constitutional monarchy.

He had in the meantime also assisted his father in the family's trading firm and worked as a house tutor.

After some years spent as a teacher at the Cathedral School of Roskilde, he founded the political journal Fædrelandet together with his friend Christian Georg Nathan David.

Jensen painted in 1837 a portrait of Johannes Dam Hage which is today exhibited in Nivaagaards Malerisamling.
