Methylene (IUPAC name: methylidene, also called carbene or methene) is an organic compound with the chemical formula CH 2 (also written [CH 2] and not to be confused with compressed hydrogen, which is also denoted CH 2). It is a colourless gas that fluoresces in the mid-infrared range, and only persists in dilution, or as an adduct.

甲烯（英語： Methylene ）在化學中是指由一個碳原子和兩個氫原子組成的化合物，又稱亞甲基或甲烯基 [2] ，其化學式為CH 2 。 在自然狀態下，不會存在甲烯，除非是在低溫、低壓的特殊狀態下，才可能有此種不穩定狀態的化合物。

a Parameters not given were fixed at zero. The numbers in parentheses are one standard deviation from the least-squares fit in units of the last quoted digit. b These parameters were fixed at values determined from a fit to non-rigid bender calculations for 13 CH 2 by Jensen et al. []. c These parameters were fixed to 12 CH 2 values.
