Bartholomäus Metlinger (born in Augsburg – died c. 1491) was a German physician of the Late Middle Ages.
He was city physician (Stadtarzt) in Nördlingen from 1476 to 1483, when he took the same position in Augsburg, probably succeeding his late father Peter Metlinger.
His most famous work, Kinderbüchlein ('Little Book on Children'), was published on 7 December 1473, being retitled in later editions as Ein Regiment der jungen Kinder ('A Guide on Young Children').
In it, Metlinger deals with the care of infants and small children up to the age of seven.
The book describes several childhood diseases and their treatments, besides providing educational advice.
