  We obtain new bounds on effective ALP-neutrino interactions from their
loop-level impact on the ALP couplings to electroweak gauge bosons $\gamma Z$,
$ZZ$ and $W^+W^-$. Both types of interactions are connected via the chiral
anomaly, which allows to overcome the fermion mass suppression of tree-level
analyses. ALP couplings to charged leptons are considered simultaneously with
ALP-neutrino ones, as required by gauge invariance. Complete one-loop
computations are presented together with relevant kinematic limits. We leverage
data obtained from rare meson decay measurements alongside observations from
collider experiments, among others. The novel constraints are particularly
competitive for ALP masses $\gtrsim 100$ MeV, evidencing the powerful potential
of future ALP searches at colliders which target its couplings to electroweak
gauge bosons.
