Psi Cassiopeiae (ψ Cassiopeiae) is a binary star 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;{{citation |title=Vizier |url=http://vizier.u-strasbg.fr/viz-bin/VizieR-S?HIC%206692 |access-date=2009-04-13}} it is a double star, designated CCDM J01259+6808AB,{{cite simbad|title=* psi Cas|access-date=2009-04-13}} 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,{{Citation |last=Norton |first=Arthur P. |title=Norton's Star Atlas |year=1973 |page=[https://archive.org/details/nortonsstaratlas0000nort/page/118 118] |publisher=Gall & Inglis |isbn=0-85248-900-5 |url=https://archive.org/details/nortonsstaratlas0000nort/page/118 }} which is itself another double;{{cite simbad | title=BD+67 124 |access-date=2009-04-13}} CD comprises a 9.4 magnitude component C and a 10 magnitude component D.{{citation |title=VizieR Detailed Page |url=http://vizier.u-strasbg.fr/viz-bin/VizieR-S?CCDM%20J01259%2b6808CD |access-date=2009-04-13}}
