Rautaruukki is a Finnish pusher vessel owned and operated by ESL Shipping. It is part of the Finnpusku integrated tug and barge system developed in the 1980s by Finnlines, a Finnish shipping company that also managed the vessel until 2003, in co-operation with Rautaruukki for the transportation needs of the steel company. Rautaruukki, built by Hollming in Rauma, Finland, was delivered on 30 October 1986 and has since been used mainly to supply raw materials to the Raahe Steel Works.

Rautaruukki has an identical sister vessel, Steel, which was delivered in 1987 as Finn. The vessel capsized in 1990, but was rebuilt, renamed and returned to service in 1991.
