Dimetil selenida adalah sebuah senyawa organoselenium dengan rumus kimia (CH₃)₂Se. Cairan nirwarna dan berbau busuk ini adalah selenoeter yang paling sederhana. Senyawa ini terdapat dalam jumlah sedikit di lingkungan anaerobik^[1] dan di atmosfer akibat biometilasi selenium.^[2]^[3]

Dimetil selenida dibuat dengan mereaksikan sumber Se²⁻ dengan agen metilasi elektrofilik seperti metil iodida:

Na₂Se + 2 CH₃I → (CH₃)₂Se + 2 NaI

Panjang ikatan karbon–selenium adalah 1,943 Å dan sudut ikatan C–Se–C adalah 96,2°, sebagaimana ditentukan melalui spektroskopi gelombang mikro rotasional.^[4]^[5] Dimensi serupa pada 1,98 Å dan 98° ditemukan melalui difraksi elektron gas.^[6]^[7]
