Flunitrazepam, sold under the brand name Rohypnol among others, is a benzodiazepine used to treat severe insomnia and assist with anesthesia. As with other hypnotics, flunitrazepam has been advised to be prescribed only for short-term use or by those with chronic insomnia on an occasional basis.

Flunitrazepam was patented in 1962 and came into medical use in 1974. Nicknamed "roofies" or "floonies", it is widely known for its use as a date rape drug.
