IceCube has recently detected high energy astrophysical neutrinos for the first time. While many known astrophysical processes are anticipated to create high energy neutrinos, the origin of the observed neutrinos remains unclear. In this talk I will first present evidence disfavoring the Milky Way as the primary origin of the flux based on anisotropy arguments. I will also consider a promising extragalactic source of high energy astrophysical neutrinos – gamma ray bursts. I will present a detailed description of the expected neutrino flux from GRBs and then use the measured IceCube flux to constrain several unknown GRB properties.
