An '''metano''' ([[Ingles]]: ''methane''; {{IPAc-en|US|ˈ|m|ɛ|θ|eɪ|n}} o {{IPAc-en|UK|ˈ|m|iː|θ|eɪ|n}}) iyo sarong [[kompuwestong kimikal]] na may pormulang kimikal na CH<sub>4</sub> (sarong atomo nin [[karbon]] sagkod apat na atomo nin [[hidroheno]]). Ini iyo sarong grupong-14 na hydride asin an pinakasimpleng [[alkane]], sagkod iyo pangenot man na konstituente kan [[natural gas]]. An relatibong abundante kan metano sa [[Kinaban]] iyo minahimo saiya bilang sarong ekonomikal na panggatong, alagad an pagguno asin pag-ataman kaini iyo minatao nin teknikal na problema huli sa istadong [[gas]] kaini sa irarom nin normal na kondisyon para sa [[temperatura]] asin [[presyon]].

An mga natural na metano iyo nakukua sa irarom nin daga asin sa irarom kan kadagatan, sagkod iyo napoporma sa parehong heyolohikal asin biyolohikal na mga proseso. An pinakadakulang gunuan nin metano iyo sa irarom kan kadagatan sa porma nin "methane clathrates". Kapag an metano naabot an luwas asin an atmospera, bistado na ini bilang atmosperikong metano.<ref name=":17">{{Cite journal|last1=Khalil|first1=M. A.
