Provided is a preparation method for a mesoporous zeolite, particularly a method for preparing mesoporous zeolite through a simple process without using costly materials such as an organic amine template or a surfactant. The method includes 1) forming a synthetic zeolite gel by mixing a silica precursor, an aluminum precursor and water and aging the resulted mixture; 2) carrying out zeolite synthesis by subjecting the synthetic zeolite gel to a hydrothermal reaction; 3) cooling the synthesized zeolite from the above step 2), then adding a basic solution thereto and allowing them to react, thereby obtaining a mesoporous zeolite slurry; and 4) washing the mesoporous zeolite slurry with water, drying and firing it, thereby obtaining a mesoporous zeolite.
