The present invention relates to a cathode slurry composition for a lithium secondary battery, a cathode comprising same, and a lithium secondary battery. More specifically, when a cathode for a lithium secondary battery is manufactured by comprising a slurry coating process, the cathode is manufactured using a thixotropic cathode slurry composition capable of ensuring the flowability to flexibly respond to a change in slurry coating rate, so that the processability can be increased in the manufacture of the cathode for a lithium secondary battery.
