Stadion Željezare is a football stadium in Nikšić, Montenegro.

It is situated near the bigger FK Sutjeska Stadium.

The stadium is the home ground of FK Čelik Nikšić.

Following successful results of FK Čelik and promotion to the Montenegrin First League, in 2012, the owners made all-seated stands at Stadion Željezare.

The stadium didn't met UEFA criteria for European competitions, so FK Čelik played their European matches on neighbouring FK Sutjeska Stadium.
