Mercuric amidochloride is an inorganic compound with the formula HgNH₂Cl.
 It consists of a zig-zag 1-dimensional polymer (HgNH₂)ₙ with chloride counterions.
It arises from the reaction of ammonia and mercuric chloride.
 Addition of base converts it into "Millon's base", which has the formula [Hg₂N]OH·(H₂O)ₓ.  A variety of related amido and nitrido materials with chloride, bromide, and hydroxide are known.

Before the toxicity of mercury was appreciated, mercuric amidochloride, known as "ammoniated mercury", was used as a topical antiseptic and disinfectant.
