Street Lethal is the first studio album by the American heavy metal band Racer X, released on January 1, 1986 through Shrapnel Records.

found Street Lethal "a pretty good album despite the occasional over-emphasis on 'melt-down' guitar pyrotechnics"; he praised the song structures, which he thought would more likely turn up on a Van Halen album, and the band's musicianship which "would put to shame many of the so-called 'big names' of heavy rock.

"[5] Because of Jeff Martin's vocals and Paul Gilbert's rhythm guitar work, Rock Hard reviewer found similarities with the early works of Japanese bands Anthem and Loudness and concluded that "if you are on speed metal with level and melody, you can also blindly access this product from Mike Varney's inexhaustible talent supply".

[6] Andy Hinds at AllMusic called Street Lethal "essentially a showcase for then teenaged guitar prodigy Paul Gilbert" and "skillfully executed, Judas Priest-style metal".

Martin's singing was also likened to that of Judas Priest's Rob Halford and the rhythm section praised for "their part in maintaining the excitement."
