  Supernova remnants (SNRs) have long been hypothesized as the main source of
Galactic Cosmic Rays up to PeV energies. Some of them have indeed been shown to
accelerate protons to TeV energies and above. But which of them are indeed
efficient accelerators of protons and nuclei? And up to which energies can they
accelerate these particles? Measurements of non-thermal emission, especially in
the X-ray and gamma-ray regimes, are essential to answer these questions. The
High-Altitude Water Cherenkov (HAWC) observatory, surveying the northern TeV
gamma-ray sky, is currently the most sensitive wide field-of-view survey
instrument in the VHE (very-high-energy, $>$100 GeV) range. With more than
three years of data recorded, HAWC is ideally suited for an unbiased survey of
gamma-ray emission from galactic SNRs, particularly at TeV energies and above.
In this proceeding, I will give an overview of recent measurements of VHE
gamma-ray emission from SNRs with the HAWC Observatory. Combined with data from
other wavelengths, these measurements are used to derive information about the
underlying particle populations such as the maximum acceleration energy and
whether leptonic or hadronic processes are responsible for the emission.
