"Mechanix" is a song by the American thrash metal band Megadeth. It is the eighth and final track from their debut studio album, Killing Is My Business... and Business Is Good!, released in 1985 under Combat Records. "Mechanix" has been featured on several Megadeth releases, including multiple greatest hits compilations and live albums.

The song was performed live by Megadeth frontman Dave Mustaine's first two bands, Panic, and Metallica. The song was included on several Metallica demo tapes, including Power Metal and No Life 'Til Leather. After Mustaine was ejected from the band, Metallica reworked the song into "The Four Horsemen", which was featured on their 1983 debut album Kill 'Em All. In the years following its release, there has been dispute over the track's songwriting credits.
