A multilayer ceramic electronic component includes a ceramic body including dielectric layers and first and second internal electrodes alternately laminated with the respective dielectric layers disposed therebetween, and first and second external electrodes disposed on first and second external surfaces of the ceramic body to be connected to corresponding internal electrodes, respectively. A longest distance from the first external electrode to the second external electrode is denoted by La, a shortest distance from the first external electrode to the second external electrode is denoted by Lb, and Lb/La is greater than zero to 0.6 or less.
