"Know Your Enemy" is a song by American rock band Rage Against the Machine. It features Tool vocalist Maynard James Keenan on vocals during the bridge section, and Jane's Addiction drummer Stephen Perkins playing additional percussion.
Allmusic describes the song as "immediately memorable" and "surprisingly straightforward" while music critic Joel McIver cited it as "a standout track" of the album.
The song, like many others in the album, contains anti-war and anti-authoritarian lyrics. The song's main message is that the American government is contradictory when it touts itself as the land of the free yet is run by an elitist enterprise, and that you should question authority figures who determine what you are able to believe.
That message is evident in lines such as, "What? The land of the free? Whoever told you that is your enemy!", "As we move into '92, still in a room without a view!" and "Yes I know my enemies! They're the teachers that taught me to fight me!"
