The invention discloses a high-toughness austenite type high-manganese steel plate and a production method thereof. The steel plate consists of the following chemical components in percentage by massof 0.30-0.40% of C, 0.20-0.40% of Si, 23.50-25.50% of Mn, 7.0-7.5% of Cr, 0.020-0.040% of Al, 0.020-0.040% of Nb, less than or equal to 0.008% of P, less than or equal to 0.003% of S and the balance Fe and inevitable impurities. The production method for the steel plate comprises processes of steel-making, continuous casting, heating, rolling and thermal treatment. The chemical components of the steel plate adopt C, Mn and Cr solid solution strengthening; and the obtained steel plate has the characteristics of being high in compactness, relatively high in strength grade, high in ductility, lowin yield ratio, excellent in low-temperature impact toughness and the like, can meet requirements of the high-toughness austenite type high-manganese steel plate, has relatively good comprehensive performances and welding performances, and is relatively low in cost.
