We examine a scenario where the Higgs is part of an approximate conformal field theory, and has
a scaling dimension greater than one. Such an unparticle Higgs (or
Unhiggs) can still break electroweak symmetry and unitarize WW
scattering, but its gauge couplings are suppressed. An Unhiggs model
has a reduced sensitivity of the weak scale to the cutoff, and can
thus provide a solution to the little hierarchy problem.
