Dimethyl telluride is an organotelluride compound, formula (CH₃)₂Te, also known by the abbreviation DMTe.

This was the first material used to grow epitaxial cadmium telluride and mercury cadmium telluride using metalorganic vapour phase epitaxy.^[2][3]

Dimethyl telluride as a product of microbial metabolism was first discovered in 1939.^[4] Dimethyl telluride is produced by some fungi and bacteria (Penicillium brevicaule, P. chrysogenum, and P. notatum and the bacterium Pseudomonas fluorescens).^[5]

The toxicity of DMTe is unclear. It is produced by the body when tellurium or one of its compounds are ingested. It is noticeable by its garlic-like smell (resembles rotting garlic in the absence of air). Tellurium is known to be toxic.^[6]
