PROBLEM TO BE SOLVED: To obtain a fiber-reinforced composite material that is lightweight, has excellent mechanical properties such as strength, modulus of elasticity, etc., and impact resistance and a prepreg for producing a fiber-reinforced composite material that is lightweight and has excellent mechanical properties such as strength, modulus of elasticity, etc., and impact resistance. SOLUTION: The fiber-reinforced composite material is a cured product of a thermosetting resin composition that comprises a reinforcing fiber and a matrix resin, in which a part or the whole of the matrix resin has 0.001-1GPa tensile modulus measured at 23°C and≥30% tensile elongation at break measured at 23°C. The prepreg is obtained by impregnating a reinforcing fiber with a thermosetting resin composition having 0.001-1GPa tensile modulus measured at 23°C and≥30% tensile modulus measured at 23°C.
