We show that the Hall coefficient RH of a doped two-dimensional Mott insulator is temperature dependent in the state where long-range magnetic order vanishes. The Hall number nH=RH-1 is linear in the doping density at high temperatures and decreases monotonically with decreasing temperature. At low temperatures RH diverges, indicating the possible onset of a phase with spontaneous chirality.
