Thundersteel is the sixth studio album by the American heavy metal band Riot, released after coming back from a period of inactivity in the mid-1980s.

The record's title song appears as a bonus track on 2013 album "Possession" by the Polish heavy metal band Crystal Viper.

The song "Flight of the Warrior" was covered by the Swedish heavy metal band HammerFall on their 2008 album Masterpieces.

A cover of "Flight of the Warrior" also appears as a bonus track on the 2013 album Beneath the Surface by German metal band Alpha Tiger who've performed the song live as well.

The album's sound has been described as power metal;[7] with AllMusic writer Brian O'Neill going into great detail describing what all went into its sound, saying, "The disc takes cues from everything that was metal at the time, combining classic European styles reminiscent of Judas Priest's heavier moments (a premonition for Painkiller), thrashing guitars and pounding percussion indicative of the then-burgeoning underground thrash movement (it's got more riffs than Anthrax ever had), and undertones of the hair metal that was riding the charts at the time (especially in appearance) into a cohesive moment of refined ferocity.
