  We discuss the leptonic ALP portal as a simple scenario that connects
observed discrepancies in anomalous magnetic moments to the Dark Matter relic
abundance. In this framework an axion-like particle in the multi-MeV range
couples to SM leptons and a DM fermion, with mass above the ALP mass but below
a GeV. The ALP contributes to $(g-2)_\mu$ and $(g-2)_e$ dominantly through
2-loop Barr-Zee diagrams, while the DM abundance is generated by $p$-wave
annihilation to ALP pairs. Constraints from beam-dump experiments, colliders
and CMB probes are very stringent, and restrict the viable parameter space to a
rather narrow region that will be tested in the near future.
