John Butter, M.D. (1791–1877) was an English ophthalmic surgeon.

Life
Born at Woodbury, Devon, on 22 January 1791, he was educated at Exeter grammar school, and studied for the medical profession at Devon and Exeter Hospital. He obtained the M.D. degree at the University of Edinburgh in 1820, and was chosen a fellow of the Royal Society in 1822.

Butter was appointed surgeon of the South Devon Militia, and later settled at Plymouth, where he concentrated on diseases of the eye. Along with Dr. Edward Moore, he was the originator of the Plymouth Eye Dispensary. He lost one eye through ophthalmic rheumatism, contracted by exposure while examining recruits for the Crimean War, and in 1856 became totally blind.
