Psi Cassiopeiae (ψ Cassiopeiae) is a binary star[11] system in the northern constellation of Cassiopeia.

The primary component, ψ Cassiopeiae A, is an orange K-type giant with an apparent magnitude of +5.0;[12][13] it is a double star, designated CCDM J01259+6808AB,[14] with a fourteenth magnitude star (component B) located 3 arcseconds from the primary. Located about 25 arcseconds distant there is a 9.8 magnitude optical companion CCDM J01259+6808CD, designated ψ Cassiopeiae B in older star catalogues,[12] which is itself another double;[12][15] CD comprises a 9.4 magnitude component C and a 10 magnitude component D.[16]
