Constantine J. Hering (January 1, 1800 – July 23, 1880) was a physician who was an early pioneer of homeopathy in the United States.

Hering was born in Oschatz, and studied medicine at the University of Leipzig where his interest in homeopathy began.

Following his graduation from the University of Würzburg in 1826 he received a commission from the King of Saxony to travel to Surinam on a natural history expedition.

He devoted much study to cures for the bites of venomous serpents and for hydrophobia, and developed many of Hahnemann's theories.

Another of his sons was Hermann S. Hering, who, for a time, lectured and conducted research at Johns Hopkins University, and later became a prominent figure in the Christian Science church.
