Neutron stars are one of the earliest and best studied high energy sources.They were first discovered as pulsars, a story which is one of the highlights of 20th century astrophysics, and they are linked to a number of other phenomena, including supernovae, short GRBs and Kilonovae. They are among the most promising sources for producing multiple non-electromagnetic signals, including gravitational waves, cosmic rays and very high energy neutrinos. Recently, a sub-class of short gamma-ray bursts arising from neutron star megers was, for the first time, observed both via gravitational waves, as well as electromagnetically, establishing multi-messenger astrophysics as a new approach to understand cosmic high energy objects. I will discuss some of the latest observational and theoretical developments in the Neutron Star, GRB, Kilonova and multi-messenger fields.
