15 Camelopardalis is a triple star[1] system in the northern circumpolar constellation of Camelopardalis. It has the variable star designation DV Camelopardalis; 15 Camelopardalis is the Flamsteed designation. This is just visible to the naked eye as a dim, blue-white hued star with a baseline apparent visual magnitude of 6.13.[2] It is a probable (99%) member of the Cas-Tau OB association.[1]

This system includes a double-lined spectroscopic binary with an orbital period of 6.7 days and a large eccentricity of around 0.48, plus a third component in a wider orbit. The close pair consist of a very slowly rotating helium-weak star plus an ordinary mid-B-type star with a more rapid rotation rate.[3] Together they form an Algol-type eclipsing binary with a depth of about 0.2 magnitude.[1] The third component is a slowly pulsating B-type star.[3]
