The Fermi Gamma-ray Space Telescope has firmly identified GeV emission from more than a dozen supernova remnants (SNRs) in its first years of operation. Long thought to be capable of supplying the high energy cosmic rays in the Galaxy, SNR shocks are ideal sites to study cosmic-ray acceleration. Here we review the SNRs detected by Fermi-LAT, and discuss their properties. The population of detected remnants spans a large range of ages and environments, allowing for a comparative study of acceleration efficiency. The inclusion of gamma-ray data in multi-wavelength models improves our general understanding of these SNRs, constraining physical parameters including the magnetic field, gas density and energetics.
