HEASA 2017 is the fifth conference in the annual series "High Energy Astrophysics in Southern Africa". Its goal is to bring together scientists from the southern African region, the African continent, and around the world, with an interest in high-energy astrophysical phenomena. Topics discussed include gravitational wave astrophysics, cosmology, theoretical astrophysics, multi-wavelength and multi-messenger observational aspects of active galactic nuclei, galaxy systems, gamma-ray bursts, X-ray/gamma-ray binaries, supernovae and supernova remnants, neutron stars, pulsars and pulsar wind nebulae, cataclysmic variables, and modern aspects of astro-particle physics.
