A leading candidate for astrophysical dark matter (DM) is a massive particle in the range from 50 GeV/c^2 to greater than 10 TeV/c^2 and an interaction cross section on the weak scale. The self-annihilation of such particles in astrophysical regions of high DM density can generate stable secondary particles including very high energy gamma rays with energies up to the DM particle mass. Dwarf spheroidal galaxies of the Local Group are attractive targets to search for the annihilation signature of DM due to their proximity and large DM content. We report on gamma-ray observations taken with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) of several dwarf galaxy targets and discuss the implications of these measurements for the parameter space of DM particle models.
