CS Camelopardalis (CS Cam; HD 21291) is a binary star in reflection nebula VdB 14, in the constellation Camelopardalis. It is a 4th magnitude star, and is visible to the naked eye under good observing conditions.

It forms a group of stars known as the Camelopardalis R1 association, part of the Cam OB1 association. The near-identical supergiant CE Camelopardalis is located half a degree to the south.

As a binary star, CS Cam is designated as Struve 385 (STF 385, Σ385).[15]

The primary component, CS Camelopardalis A, is a blue-white B-type supergiant with a mean apparent magnitude of 4.21m. The star was found to be a variable star when the Hipparcos data was analyzed. It was given its variable star designation in 1999.[17] It is classified as an Alpha Cygni type variable star and its brightness varies from magnitude 4.19m to 4.23m. Its companion, CS Camelopardalis B, is a magnitude 8.7m blue giant star located 2.4 arcseconds from the primary.[18]
