The 2nd Chemical Battalion is a United States Army chemical unit stationed at Fort Hood, Texas, United States, and is part of the 48th Chemical Brigade. The battalion can trace its lineage from the 30th Engineer Regiment (Gas and Flame) and has served in World War I, World War II, Korean War, Operation Desert Storm, and Operation Iraqi Freedom.

The 2nd Chemical Battalion currently (June 2019) consists of the Headquarters and Headquarters Company (Hellfire) and 181st Chemical Company (Double Dragons) at Fort Hood (then known as Fort Cavazos), Texas, the 172nd Chemical Company (Gladiators) at Fort Riley, Kansas and the 63rd Chemical Company (Dragon Masters) at Fort Campbell, Kentucky/Tennessee. The 68th Chemical Company (Responders) was formerly part of the battalion but was deactivated on September 27, 2024 at Fort Cavazos. The unit is sometimes incorrectly referred to as the "2D CBRN Battalion" where CBRN stands for Chemical, Biological, Radiological, and Nuclear. However the correct designation for the unit is "2D Chemical Battalion (CBRN)."
