10 Cassiopeiae (10 Cas) is a blue-white giant star in the constellation Cassiopeia, about 960 light years away.

10 Cassiopeiae is a B9 giant star. It shows emission lines in its spectrum and is classified as a Be star. It shows slight variations in its brightness, between magnitudes 5.54 and 5.59.

At an age of 218 million years, 10 Cassiopeiae has expanded away from the main sequence after exhausting its core hydrogen and now has a radius about eight times that of the Sun. With an effective temperature of about {{val|fmt=commas|11,000|ul=K}}, it emits nearly a thousand times the luminosity of the Sun.
