Minimal Flavor Violation (MFV) ofers an appealing framework for exploring physics beyond the Standard Model. Interestingly, within the MFV framework, a new colorless feld that transforms non-trivially under a global SU(3)3 quark favor group can naturally be stable. Such a new feld is thus a promising dark matter candidate, provided it is electrically neutral. We extend the MFV framework for dark matter and demonstrate that dark matter can naturally be multi-component across a broad parameter space. For illustration, we consider a gauge singlet, favor triplet scalar feld and identify parameter spaces for multicomponent dark matter, where only the lightest favor component is absolutely stable and heavy favor components are decaying with lifetimes sufciently longer than the age of the universe. Phenomenological, cosmological and astrophysical aspects of multi-component favored dark matter are briefy discussed.
