We show that decaying axino dark matter with R-parity violation can explain the observed excess of the 130 GeV gamma-ray line from the Galactic center in the Fermi data. The branching fraction Of the axino decay into monochromatic photons can be O(1), and constraints from continuum gamma-rays and the anti-proton flux are ameliorated. The Pecce-Quinn scale of O(10(13)-10(14)) GeV and the R-parity violation parameter of O(10(-12)-10(-11)) are cosmologically favored. (C) 2013 Elsevier B.V. All rights reserved.
