Nalorphine (; also known as '''N-allylnormorphine; brand names Lethidrone and Nalline') is a mixed opioid agonist–antagonist with opioid antagonist and analgesic properties. It was introduced in 1954 and was used as an antidote to reverse opioid overdose and in a challenge test to determine opioid dependence.

Nalorphine was the second opioid antagonist to be introduced, preceded by nalodeine (N''-allylnorcodeine) in 1915 and followed by naloxone in 1960 and naltrexone in 1963. Due to potent activation of the κ-opioid receptor, nalorphine produces side effects such as dysphoria, anxiety, confusion, and hallucinations, and for this reason, is no longer used medically.
