Dimethyl selenide is the organoselenium compound with the formula (CH₃)₂Se. This colorless, malodorous, liquid is the simplest selenoether. It occurs in trace amounts in anaerobic environments.^[1]

Dimethyl selenide is prepared by treating Se^2- sources with electrophilic methylating agents such as methyl iodide:

Na₂Se + 2 CH₃I → (CH₃)₂Se + 2 NaI
