Abstract: We show that optically excited electrons by a circularly polarized light in a semiconductor with spin-orbit coupling subject to a weak electric field will carry a Hall current transverse to the electric field. This light-induced Hall effect is a special type of anomalous Hall effect and is a result of quantum interference of the light and the electric field and can be viewed as a physical consequence of the spin current induced by the electric field. The light-induced Hall conductivity is calculated for the $p$-type GaAs bulk material and the $n$-type and $p$-type quantum well structures.
