Bis(2-chloroethyl)ethylamine is the organic compound with the formula C₂H₅N(CH₂CH₂Cl)₂. Often abbreviated HN1, it is a powerful vesicant and a nitrogen mustard gas. HN1 was developed in the 1920s and 1930s to remove warts and later as a military agent. Because of the latter use, it is a Schedule 1 chemical within the Chemical Weapons Convention and therefore use and production is strongly restricted. It has never been used in warfare.

It is an oily liquid with a colorless to pale yellow appearance and a faint fishy or musty odor. HN1 is also an alkylating agent.
