We briefly review the characteristics of super-Eddington (SED) states which arise in various astrophysical systems. These include classical nova eruptions, giant LBV eruptions, super-massive objects (SMOs) and very high accretion rate flows. The former two have ample observational data to establish the existence of SED states and learn of their behavior. When applying this understanding to the latter two, very interesting conclusions can be drawn. For example, "super-Eddington" black hole growth through accretion is possible, but SMOs cannot provide the photoionizing radiation in the early Universe, though they can provide seed black holes.
