In this thesis, we investigate compact objects made of dark matter. We find the hydrostatic equilibria for compact objects consisting of both fermionic and bosonic dark matter. The dark matter can possibly have self-interactions that are independently motivated by sub-galactic structure problems in the collisionless cold dark matter paradigm. We find that the self-interactions necessary for resolving sub-galactic structure problems can completely change the morphology of dark compact objects. We comment upon observational signatures of these dark stars, in particular the prospect of receiving gravitational radiation from binary mergers.
