We explore an intriguing possibility to test the type-II seesaw mechanism of neutrino mass generation at the Large Hadron Collider (LHC). We show that the lepton-number-violating signatures of heavy Majorana neutrinos N(i) (for i = 1, 2, 3) and doubly-charged Higgs bosons H(+/-+/-) can be closely correlated with each other in a class of TeV-scale type-II seesaw models. Taking the minimal version of such models for example, we calculate the cross sections of pp -> l(alpha)(+/-)l(beta)(+/-) X processes mediated separately by N(1) and H(+/-+/-), and illustrate their nontrivial correlation at the LHC.
