The Mertainen is an iron ore deposit and mine in Lapland, Sweden, Sweden. It is located about 30 km southeast of the town of Kiruna.[1] In December 2016 Luossavaara-Kiirunavaara AB closed the mine for indefinite time.[2] Re-opening the mine remains a possibility according to LKAB executive Magnus Arnkvist.[2]

The ore is chiefly magnetite with small amounts of hematite.[1] The deposit has a few small massive magnetite bodies and a larger volume of low grade ore made up of host-rock intruded by magnetite veins.[1] The host rock is made up of scapolite and biotite-altered Syenite Porphyry.[1] The Syenite Porphyry display magnetite nodules.[1]

Most of the deposit has a low phosphorus grade (0.05%) but in the northeast phosphorus grades are higher (0.2 to 0.9%).[3]
