We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we choose the 3-3-1 model. We consider a variety of processes: q anti-q -> Y^{ ++} Y^{ --}, u anti-d -> Y^{ ++} Y^{ -}, anti-u d -> Y^+ Y^{ --}, q anti-q -> Y^{ ++} e^{ -} e^{ -}, q anti-q -> phi^{ ++} phi^{ --}, u anti-d -> -> phi^{ ++} phi^{ -}, and anti-u d -> phi^{ +} phi^{ --}, where Y and phi are vector and scalar bileptons, respectively. Given the present low-energy constraints, we find that at the Tevatron, vector bileptons are unobservable, while light scalar bileptons (M_phi <= 300 GeV) are just barely observable. At the LHC, the reach is extended considerably: vector bileptons of mass M_Y <= 1 TeV are observable, as are scalar bileptons of mass M_phi <= 850 GeV.
