Daniel Jensen Adzer (17 January 1732 – 3 April 1808) was a Danish medallist (i.e., medal maker).

In 1754, he traveled to Paris, where he met another young goldsmith from Copenhagen, J. H. Wolff, who inspired him to pursue a career as a medallist.

His first work as a medallist was the reverse side of Magnus Gustav Arbien's medal to the Art Academy's patron, A. G. Moltke.

In 1766, he was created a full member of the Art Academy after submitting a new medal to A. G. Moltke as his reception piece.

These included medals commemorating the death of Frederick V and the anointing of Christian VII as well as medals to Frederick, Hereditary Prince of Denmark, and the Queen Dowager Juliane Marie, members of the Bernstorff family, and the scholars Langebek, Hielmstjerne and Suhm.
