The mixed-state Hall resistivity \ensuremathρxy and the longitudinal resistivity \ensuremathρxx in superconducting MgB2 thin films have been investigated as a function of the magnetic field over a wide range of current densities from 102 to 104 A/cm2. We observe a universal Hall scaling behavior with a constant exponent \ensuremathβ of 2.0\ifmmode±\else\textpm\fi0.1 in \ensuremathρxy=A\ensuremathρxx^\ensuremathβ, which is independent of the magnetic field, the temperature, and the current density. This result can be interpreted well within the context of recent theories.
