Bakteri (dari kato Latin bacterium; jamak: bacteria) adolah kalompok organisme nan indak mampunyoi membran inti sel.[4] Organisme ko tamasuak ka dalam domain prokariota jo baukuran ketek sangaik (mikroskopik), sarato mampunyoi paran gadang dalam kahidupan di bumi.[4] Babarapo kalompok bakteri tanamo sabagai agen panyabab infeksi jo panyakik, samantaro kalompok lainnyo dapek maagiah manpaaik dibidang pangan, ubek, jo industri.[5] Struktur sel bakteri relatif sederhana: tanpa nukleus/inti sel, karangko sel, jo organel-organel lain sarupo mitokondria dan kloroplas.[5] Hal ikolah nan manjadi pambeda antaro sel prokariot jo sel eukariot nan labiah kompleks.[6]

Bakteri dapek ditamukan di ampia sado tampek: di tanah, aia, udaro, dalam simbiosis jo organisme lain ataupun sabagai agen parasit (patogen), bahkan dalam tubuah manusia.[7][8][9][10] Pado umumnyo, bakteri baukuran 0,5-5 μm, tapi ado bakteri tatantu nan dapek mancapai diameter 700 μm, iyolah Thiomargarita.[11] Umumnyo mampunyoi dindiang sel, sarupo sel tumbuahan jo cindawan, tapi jo bahan pambantuak nan amaik babeda (peptidoglikan).[12] Babarapo jinih bakteri basipaik motil (talok manggarik) jo mobilitasnyo ko dek adonyo flagel.[13]
