'''Metana''' adalah [[hidrokarbon]] paling sederhana yang berbentuk [[gas]] dengan [[rumus kimia]] [[Karbon|C]][[Hidrogen|H]]<sub>4</sub>. Metana murni tidak berbau, tapi jika digunakan untuk keperluan komersial, biasanya ditambahkan sedikit bau [[belerang]] untuk mendeteksi kebocoran yang mungkin terjadi.
