  Supernova remnants (SNRs) are widely considered the most likely source of
cosmic rays below the knee ($10^{15}$ eV). Studies of GeV and TeV gamma-ray
emission in the vicinity of SNRs, in combination with multi-wavelength
observations, can trace and constrain the nature of the charged particle
population believed to be accelerated within SNR shocks. They may also speak to
the diffusion and propagation of these energetic particles and to the nature of
the acceleration mechanisms involved. We report here on recent observations of
SNRs with VERITAS, including the discoveries of VHE gamma-ray emission from
from G120.1+1.4 (Tycho's SNR) and from the northwest shell of G78.2+2.1
(gamma-ray source VER J2019+407, which was discovered as a consequence of the
VERITAS Cygnus region survey).
