Dimethyl phthalate (DMP) is an organic compound and phthalate ester. it is a colourless and oily liquid that is soluble in organic solvents, but which is only poorly soluble in water (~4 g/L).

It is used in a variety of products and is most commonly used as insect repellent such as ectoparasiticide for mosquitoes and flies for animal livestock. The short-chain or low molecular weight phthalate is also frequently used in consumer products such as cosmetics, ink, soap, household cleaning supplies, etc. Other uses of DMP include solid rocket propellants and plastics.

The U.S Environmental Protection Agency has classified Dimethyl phthalate as not classifiable for human carcinogenicity. Its oral LD50 is 4390 to 8200 mg/kg bw/d in rats and the dermal LD50 is 38000 mg/kg bw in rats and more than 4800 mg/kg bw in guinea pigs.
