'''Metana''' ({{Jawi|ميتان}}) ialah [[sebatian kimia]] dengan [[formula kimia]] CH</noinclude><small><sub>4</sub></small><noinclude>. Ia sejenis [[alkana]] yang teringkas yang merupakan komponen utama [[gas asli]]. Ia barangkalinya merupakan [[sebatian organik]] yang paling banyak dijumpai di Bumi, menjadikan ia [[bahan api]] yang menarik. Walau bagaimanapun, metana sukar diangkut dari sumbernya kerana sifat [[gas]]<nowiki/>nya dalam [[suhu dan tekanan piawai|keadaan normal]].

[[Metana atmosferik]] adalah [[gas rumah hijau]] yang agak kuat. Kepekatan metana dalam [[atmosfera Bumi]] pada tahun 1998, yang diungkapkan sebagai satu [[pecahan mol]], 1745 nmol/mol (bahagian per bilion, ppb), naik dari 700 nmol/mol pada tahun 1750. Walau bagaimanapun, tahap metana global, yang telah tinggal kebanyakannya rata sejak tahun 1998, telah meningkat kepada 1800 nmol/mol menjelang tahun 2008.
