Provided are a long fiber-reinforced polypropylene resin composition which provides a molded article excellent in a mechanical strength and an impact resistance and having a small anisotropy in a strength, so that it can suitably be used even for uses in medium-sized to large-sized molded articles, and a molded article obtained from the same. The long fiber-reinforced polypropylene resin composition comprises 35 to 75% by weight of a matrix polymer comprising a modified propylene homopolymer (A1) which is prepared by modifying a propylene homopolymer with an unsaturated carboxylic acid or a derivative thereof and which has an isotactic pentad ratio (P value) of 96% or more, a melt flow rate (230° C., 21.18N) of 80 g/10 min or more and an Mw/Mn (Q value) of 3.5 or less and 25 to 65% by weight of a glass long fiber (A2) having a length of 2 to 50 mm.
