Provided is a 6XXX series aluminum alloy sheet for a door inner panel, a preparation method therefor and an application thereof. The sheet includes, by weight percentage, 0.9-1.85% of Si, 0.15-0.4% of Fe, 0.05-0.3% of Cu, 0.05-0.15% of Mn, 0.2-0.9% of Mg, 0.01-0.03% of Ti, 0.1-0.2% of Cr, and an atomic ratio of Si to Mg is (0.9-7.9):1. The preparation method includes: mixing raw materials, and sequentially carrying out smelting and casting, homogenization-cooling and heat preservation integrated treatment, hot rolling, primary cold rolling, intermediate annealing, secondary cold rolling, solid solution, straightening, and pre-aging. The sheet of the present disclosure has a high work hardening index, small anisotropy, a high plane strain limit, good stability at room temperature and high baking yield strength, which has good mechanical properties and forming properties, and is suitable for being applied to stamping forming of door inner panels of automobiles.
