Toxicocalamus is a genus of snakes in the family Elapidae. Most species are relatively small, the largest specimen known being the holotype of the recently described Toxicocalamus ernstmayri, which measures 1.1 m snout to vent (SVL) and 1.2 m in total length (TTL), with the second longest the holotype of T. grandis (880 mm SVL, 980 mm TTL). Most species are under 800 mm in length and several are the thickness of bootlaces. In general females have longer bodies than males, but much shorter tails.
