Z Camelopardalis is a cataclysmic variable star in the constellation of Camelopardalis. It has an apparent visual magnitude which varies between 10.0 and 14.5. It is the prototype star for the family of Z Camelopardalis variable stars, dwarf novae with standstills at a brightness intermediate between their maxima and minima.
Z Camelopardalis was discovered photographically in 1904 by Henry Park Hollis during work for the Astrographic Catalogue. It is surrounded by an extensive shell thought to have been ejected in a nova explosion.
