The invention relates to a high-temperature-resistant ultra-light ceramic fiber porous elastomer material and a preparation method and application thereof.The method comprises the following steps that ceramic micron fibers, a surfactant and water are stirred at a high speed to be evenly dispersed, and ceramic micron fiber dispersion liquid is formed; and then adding a graphene oxide solution, a reducing agent and a binder, uniformly stirring, and then sequentially carrying out gel reaction, pre-freezing, freeze drying, thermal annealing treatment at 1200-1600 DEG C in an inert atmosphere for 0.1-2 hours and calcination treatment at 300-800 DEG C in an air atmosphere for 1-6 hours to prepare the high-temperature-resistant ultra-light ceramic fiber porous elastomer material. The temperature resistance limit of the prepared high-temperature-resistant ultra-light ceramic fiber porous elastomer material is not less than 1400 DEG C and can reach 1600 DEG C, and the high-temperature-resistant ultra-light ceramic fib
