A resin composition that has good heat resistance and handleability and that can produce a prepreg which has a good balance between tackyness and drapability and which causes little resin flow during prepreg molding, a prepreg that is manufactured using the resin composition, and a fiber-reinforced composite are provided. A resin composition that contains a maleimide compound, diallyl bisphenol A, and a diallyl isophthalate polymer, a prepreg in which reinforcing fibers are impregnated with the resin composition, and a fiber-reinforced composite material that is obtained by molding the prepreg are provided. 1. A resin composition that contains a maleimide compound , diallyl bisphenol A and a diallyl isophthalate polymer.2. The resin composition according to is a blend in which the following formulas are satisfied when amounts of an aromatic maleimide compound claim 1 , an aliphatic maleimide compound claim 1 , the diallyl bisphenol A and the diallyl isophthalate polymer are represented by [a1] claim 1 , [a2] claim 1 , [b] and [c] claim 1 , respectively claim 1 , in parts by mass:{'br': None, 'i': a', +[a, '[12]=100\u2003\u2003(1)'}{'br': None, 'i': 'b]≧', '[20\u2003\u2003(2)'}{'br': None, 'i': b]≦−', '×[a, '[1.42]+140\u2003\u2003(3)'}{'br': None, 'i': b]≧−', '×[a, '[3.62]+90\u2003\u2003(4)'}{'br': None, 'i': '≦[c]≦', '1565\u2003\u2003(5)'}{'br': None, 'i': '≦[a', '02]≦45\u2003\u2003(6).'}3.
