The present disclosure relates to a super absorbent polymer and a preparation method of the same, which not only has excellent basic absorption performance, but also exhibits an improved absorption rate, and the like. The super absorbent polymer includes a base resin powder containing a first cross-linked polymer of a water-soluble ethylene-based unsaturated monomer having at least partially neutralized acidic groups; and a surface cross-linked layer containing a second cross-linked polymer in which the first cross-linked polymer is additionally cross-linked by a surface cross-linking agent on the base resin powder, wherein the super absorbent polymer contains less than 9.9% by number of super absorbent polymer particles having an aspect ratio, which is defined as shortest diameter/longest diameter of each super absorbent polymer particle, of less than 0.5, a vortex time is 5 to 55 seconds by a vortex method, and a surface tension is 50 to 80 mN/m.
