383 Janina is a Themistian asteroid, approximately 46 kilometers (29 miles) in diameter. It is spectral B-type and is probably composed of primitive carbonaceous chondritic material.
It was discovered by Auguste Charlois on 29 January 1894 in Nice. The reference of the name is unknown, though it is the French name of Ioannina in Greece, as well as a common German woman's name, both of which probably descend from Johannes.
