The invention discloses a Cu-Mn bimetallic composite type low-temperature denitration catalyst and a preparation method thereof. The catalyst is prepared by using an immersion method. A chabasite molecular sieve H-SAPO-34 is taken as a carrier, and active components are composite oxides of transition metals Cu and Mn, wherein the weight percentages of the active components Cu and Mn are 2% to 10% respectively. According to the SCR catalyst disclosed by the invention, compared with a Cu-based or Mn-based catalyst of a single component, the denitration efficiency and heat stability of the catalyst are improved obviously by using a bimetallic synergistic effect, and the active temperature window of the catalyst is effectively widened; at the temperature of 180-350 DEG C, the conversion rate of NO can reach 90% or more.
