We point out that lepton number violation is possible even if neutrinos are of Dirac type, and construct a simple renormalizable model that leads to $\Delta L = 4$. We identify the signature low-energy decay of this new framework as neutrinoless quadruple beta decay and present potential candidate isotopes. In addition, an accompanying leptogenesis mechanism will be discussed that differs qualitatively from standard Dirac leptogenesis.
