NGC 1260 ist eine linsenförmige Galaxie vom Hubble-Typ S0/a im Sternbild Perseus am Nordsternhimmel. Sie ist schätzungsweise 262 Millionen Lichtjahre von der Milchstraße entfernt, hat einen Durchmesser von etwa 85.000 Lichtjahren und ist Mitglied des Perseus-Galaxienhaufens Abell 426. Gemeinsam mit PGC 12230 bildet sie ein gravitativ gebundenes Galaxienpaar.
Im selben Himmelsareal befinden sich u. a. die Galaxien NGC 1259, NGC 1264, NGC 1267, IC 310.[4]

Die Typ-IIn-Supernova SN 2006gy wurde am 16. September 2006 hier entdeckt, eine der hellsten jemals beobachteten Supernovae (etwa 100-mal stärker als eine normale Supernova).[5][6][7]
