  From the earliest extragalactic infrared studies AGN have shown themselves to
be strong infrared sources and IR surveys have revealed new populations of AGN.
I briefly review current motivations for AGN surveys in the infrared and
results from previous IR surveys. The Luminous Infrared Galaxies, which in some
cases house dust-enshrouded AGN, submillimeter surveys, and recent studies of
the cosmic x-ray and infrared backgrounds suggest that there is a population of
highly-obscured AGN at high redshift. ISO Surveys have begun to resolve the
infrared background and may have detected this obscured AGN population. New
infrared surveys, particularly the SIRTF Wide-area Infrared Extragalactic
Legacy Survey (SWIRE), will detect this population and provide a platform for
understanding the evolution of AGN, Starbursts and passively evolving galaxies
in the context of large-scale structure and environment.
