Néodimium silih tunggil datu kimia antuk simbol Nd miwah wilangan atom 60. Néodimium rumasuk ring dérét lantanida miwah dados datu tanah langka. Punika logam kapérakan sané katos, akedik maléléh énggal ring udara miwah kaayuban. Ri kala kaoksidasi, néodimium maréaksi énggal antuk ngasilang senyawa mawarna dadu, tangi/pelung miwah kuning ring paindukan oksidasi +2, +3 miwah +4.^[5] Néodimium katemuin warsa 1885 olih pawikan kimia Austria Carl Auer von Welsbach. Katemuin makéh ring mineral wijih monasit miwah bastnäsit. Néodimium nénten katemuin alami ring rupa logam utawi nénten kacampuh sareng lantanida liyanan, ketah kamurniang antuk pawigunaan umum. Yadiastun néodimium kaklasifikasiyang manados datu tanah langka, punika umum, nénten luwih langka saking kobalt, nikel, utawi témaga, miwah sacara jimbar kasebar ring kerak Gumi.^[6] Makéhan néodimium komersial ring gumi asil tambang Cina.
