  Little Higgs theories are an exciting new possibility for physics at TeV
energies. In the Standard Model the Higgs mass suffers from an instability
under radiative corrections. This ``hierarchy problem'' motivates much of
current physics beyond the Standard Model research. Little Higgs theories offer
a new and very promising solution to this problem in which the Higgs is
naturally light as a result of non-linearly realized symmetries. This article
reviews some of the underlying ideas and gives a pedagogical introduction to
the Little Higgs. The examples provided are taken from the paper "A Little
Higgs from a Simple Group", by D.E. Kaplan and M. Schmaltz.
