Webmineral</ref>}}'''Arfvedsonit''' adalah mineral amfibol natrium nang baisi kumposisi: [Na][Na<sub>2</sub>][(Fe<sup>2+</sup>)<sub>4</sub>Fe<sup>3+</sup>][(OH)<sub>2</sub><nowiki>|</nowiki>Si<sub>8</sub>O<sub>22</sub>]. Mineral ngini mangkaristal di sistim karistal prismatik monoklinik wan biasanya babantuk prisma baserat sampai baradiasi atawa kbintangan bawarna hitam pina kahijauan sampai abu-abu kabiruan.

Mineral ngini adalah mineral nang lumayan langka nang tabantuk di intrusi nefelin syenit wan pegmatit wan granit agpaitik (peralkalin) sama nang kaya batolit Golden Horn di Okanogan County, Washington (lokasi tabentuknya zektzerite). Mineral ngini kawanjua ditamui di Mont Saint-Hilaire, Quebec, Kanada; kompleks Ilímaussaq di Greenland Salatan; wan pegmatit Semenanjung Kola, [[Rusia]]. Asosiasi mineralnya meliputi nefelin, albit, aegirin, riebeckit, katoforit, dan kuarsa.

Arfvedsonit ditamuakan tahun 1823 wan ngarannnya diambil matan kimiawan Swedia Johan August Arfwedson (1792–1841).
