Present knowledge on gamma radiation that originates from cosmic-ray interactions with gas and photons in the ISM is reviewed. Basic principles of such radiation and the main observational results are described. The significance of the findings for molecular gas studies and cosmic ray studies is discussed. Present understanding of radiation from gamma-ray point sources is briefly addressed, emphasizing the possible diffuse nature of these sources.
