ATMP or aminotris(methylenephosphonic acid) is a phosphonic acid with chemical formula N(CH₂PO₃H₂)₃. It has chelating properties. It can be synthesized from the Mannich-type reaction of ammonia, formaldehyde, and phosphorous acid.

ATMP has better antiscale performance than that of polyphosphate through its excellent chelating ability, low threshold inhibition and lattice distortion process. It can prevent scale formation in water systems. ATMP is the phosphonate analog of nitrilotriacetic acid.
