  The field of TeV gamma-ray astronomy has produced many exciting results over
the last decade. Both the source catalogue, and the range of astrophysical
questions which can be addressed, continue to expand. This article presents a
topical review of the field, with a focus on the observational results of the
imaging atmospheric Cherenkov telescope arrays. The results encompass pulsars
and their nebulae, supernova remnants, gamma-ray binary systems, star forming
regions and starburst and active galaxies.
