The invention discloses a magnesium diboride superconductor doped with nanocarbon crystals and belongs to the field of superconducting materials. The magnesium diboride superconductor is prepared from boron powder, magnesium powder and nanocarbon crystals, wherein the mole ratio of magnesium powder to boron powder is 1:(1.9-2.4), and the ratio of the mass of nanocarbon crystals to the total mass of magnesium powder and boron powder is not larger than 0.09:1. The invention further discloses a preparing method of the magnesium diboride superconductor doped with nanocarbon crystals. According to the magnesium diboride superconductor doped with nanocarbon crystals and the preparing method of the magnesium diboride superconductor doped with nanocarbon crystals, doped nanocarbon crystals have little influence on the normal state resistance of magnesium diboride but can influence the superconducting transition temperature of magnesium diboride; when the doping amount is very small, the carbon element in nanocarbon crystals does not enter lattices of magnesium diboride; along with increasing of the doping amount, the carbon element gradually enters the lattices of magnesium diboride, changes the lattice parameters of magnesium diboride and then influences the superconducting transition temperature of magnesium diboride.
