  We study lepton number violation in Little Higgs model and find that the
choice of putting triplet Higgs vev equal to zero so as not to have any tree
level neutrino Majorana mass is not natural in the sense that such a term is
generated at the one loop level. We investigate the contribution of exotic
lepton number violating terms on neutrinoless double beta decay, K meson decay
and on trilepton production in $\nu$-N scattering.
