In chemistry, methylene generally refers to a carbon atom bound to two atoms. It may mean:

  • Methylene (compound) or (unsubstituted) carbene, :CH
    2
  • Methylene group or methylidene, a part of a molecule with formula =CH
    2
    , connected to another atom by a double bond, as in "methylenecyclopropene"
  • Methylene bridge or methanediyl, -CH
    2
    -, with the carbon connected to two distinct atoms, as in "methylene dichloride"

Methylene may also be:

  • An obsolete name for methanol, CH
