  The new particle recently discovered at the Large Hadron Collider has
properties compatible with those expected for the Standard Model (SM) Higgs
boson. However, this does not exclude the possibility that the discovered state
is of non-standard origin, as part of an elementary Higgs sector in an extended
model, or not at all a fundamental Higgs scalar. We review briefly the
motivations for Higgs boson scenarios beyond the SM, discuss the phenomenology
of several examples, and summarize the prospects and methods for studying
interesting models with non-standard Higgs sectors using current and future
data.
