  Generalized uncertainty principles are effective changes to the Heisenberg
uncertainty principle that emerge in several quantum gravity models. In the
present letter, we study the consequences that two classes of these
modifications yield on the physics of neutrinos. Besides analyzing the change
in the oscillation probabilities that the generalized uncertainty principles
entail, we assess their impact on the neutrino coherence length and their
possible interpretation as nonstandard neutrino interactions. Constraints cast
by present and planned neutrino experiments on the generalized uncertainty
principles parameters are also derived.
