We explore a class of models which can provide a common origin for the recently observed evidence for lepton flavor universality violation in b -> sl(+)l(-) decays, the dark matter (DM) problem, and the long-standing muon (g - 2) anomaly. In particular, both anomalies in the B meson decays and the muon (g - 2) can be explained by the additional one-loop diagrams with DM candidates. We first classify several simple models according to the new fields' quantum numbers. We then focus on a specific promising model and perform a detailed study of both DM and flavor physics. A random scan over the relevant parameter space reveals that there is indeed a large parameter space which can explain the three new physics phenomena simultaneously, while satisfying all other flavor and DM constraints. Finally, we discuss some of the possible new physics signatures at the Large Hadron Collider.
