Methanetellurol is the organotellurium compound with the formula {{chem2|CH3TeH|auto=1}}. It is the simplest organotellurium compound that has been purified in bulk. It is classified as a tellurol. A colorless gas, it decomposes to Te and methane near room temperature. It is prepared by reduction of dimethyl ditelluride using Na/Ammonia followed by protonation of the {{chem2|CH3Te−Na+}} (sodium methanetellurolate) with sulfuric acid. Few publications describe this compound as a consequence of its instability and paucity of applications.
According to IR spectroscopy, νTe-H = 1995 cm−1. For the lighter homologues, νE-H = 2342 (E = Se), 2606 (E = S), and 3710 cm−1 (E = O) for methaneselenol, methanethiol, and methanol.{{cite journal |doi=10.1080/00945717708069709|title=The Synthesis and the Raman and Infrared Spectra of Methanetellurol|year=1977|last1=Hamada|first1=K.|last2=Morishita|first2=H.|journal=Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry|volume=7|issue=4|pages=355–366}}
