The invention discloses an organic matter maturity characterization method based on mechanical properties, and belongs to the field of organic matter maturity characterization. Comprising the following steps: carrying out vitrinite reflectance measurement on a hydrocarbon source rock sample to obtain the organic matter maturity of the hydrocarbon source rock sample, and establishing an organic matter maturity sequence; measuring the Young modulus of the hydrocarbon source rock sample by using an atomic force microscope to obtain the Young modulus of the organic matters in the hydrocarbon source rock samples with different maturity degrees; combining the organic matter maturity sequence and the Young modulus, and utilizing a regression analysis method to construct an S model of the organic matter maturity and the Young modulus; measuring the Young modulus of the unknown hydrocarbon source rock sample by using an atomic force microscope, and obtaining the organic matter maturity of the unknown hydrocarbon sourc
