e-ASTROGAM (‘enhanced ASTROGAM’) is a breakthrough Observatory space mission, with adetector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated tothe study of the non-thermal Universe in the photon energy range from 0.3 MeV to 3 GeV – thelower energy limit can be pushed to energies as low as 150 keV, albeit with rapidly degrading angularresolution, for the tracker, and to 30 keV for calorimetric detection. The mission is based on anadvanced space-proven detector technology, with unprecedented sensitivity, angular and energy res-olution, combined with polarimetric capability. Thanks to its performance in the MeV-GeV domain,substantially improving its predecessors, e-ASTROGAM will open a new window on the non-thermalUniverse, making pioneering observations of the most powerful Galactic and extragalactic sources,elucidating the nature of their relativistic outflows and their effects on the surroundings. With aline sensitivity in the MeV energy range one to two orders of magnitude better than previous gen-eration instruments, e-ASTROGAM will determine the origin of key isotopes fundamental for theunderstanding of supernova explosion and the chemical evolution of our Galaxy. The mission willprovide unique data of significant interest to a broad astronomical community, complementary topowerful observatories such as LIGO-Virgo-GEO600-KAGRA, SKA, ALMA, E-ELT, TMT, LSST,JWST, Athena, CTA, IceCube, KM3NeT, and the promise of eLIS
