Nebula Orion (dipinandui jua lawan ngaran Messier 42, M42, atawa NGC 1976) adalah sabuah nebula bauran nang ada di bima sakti, baandak di subalah salatan Pandéng Orion di konstelasi Orion. Nebula ngini marupakan salah sabuting nebula paling tarang, wan kawa diitihi pakai mata talanjang di langit malam. Jaraknya  jauhnya wan nebula ngini jua marupakan wilayah ganal formasi bintang paling parak lawan bumi. Nebula M42 diparkira'akan jaraknya 24 tahun cahaya.
