RDX (Research Department Explosive or Royal Demolition Explosive), or hexogen, also known by other names, is an organic compound with the formula (CH2N2O2)3. It is white, odorless, tasteless, and widely used as an explosive. Chemically, it is classified as a nitroamine alongside HMX. It was used widely in World War II and remains common in military applications. It is lower performing and more toxic than modern replacements like TKX-50.

RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive and a key ingredient in Semtex. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, with a relative effectiveness factor of 1.60.
