  In certain backgrounds string theory exhibits quantum Hall-like behavior.
These backgrounds provide an explicit realization of the effective
non-commutative gauge theory description of the fractional quantum Hall effect
(FQHE), and of the corresponding large N matrix model. I review results on the
string theory realization of the two-dimensional fractional quantum Hall fluid
(FQHF), and describe new results on the stringy description of
higher-dimensional analogs.
