The invention discloses a lightweight high-strength proppant prepared from water-based rock debris and a preparation method thereof.The lightweight high-strength proppant is composed of water-based rock debris A and water-based rock debris B. The lightweight high-strength proppant is prepared from the water-based rock debris A and the water-based rock debris B. The water-based rock debris is used as a raw material, additives are not needed, the raw material is subjected to ball milling and uniform mixing through a reasonable mass ratio, water is added through a spraying method for granulation, and a green body is prepared; performing heat treatment by utilizing different sintering atmospheres to obtain the light high-strength proppant; a corundum phase and a mullite phase can be obtained by utilizing the water-based rock debris A and the water-based rock debris B, and the mullite phase has relatively high hardness and toughness, so that the proppant has high strength; the corundum phase has high hardness, and
