| Symbol | Nb |

Niobiwm, gyda ciwb 1cm3 wrth ei ochr.
Elfen gemegol yw **niobiwm** (gynt, **columbiwm**) gyda'r symbol `**Nb**` a'r rhif atomig 41 yn y tabl cyfnodol. Daw'r gair "niobiwm" allan o fytholeg Roeg: merch Tantalws oedd Niobe. Bathwyd y gair "columbiwm", sef yr enw gwreiddiol ar yr elfen hon, gan ddarganfyddwr yr elfen, sef Charles Hatchett a hynny yn 1801. Galwodd y mwyn yn *columbite* a'r elfen yn *columbium* ar ôl y gair barddonol am America: Columbia (o'r gair Columbus).

Mae'r elfen hon yn brin, llwyd, meddal ac yn un o'r metalau trosiannol. Fe'i ceir mewn 'pyrochlore' ac mewn 'columbite' ac fe'i cynhyrchir yn bennaf yn Brasil.
