"Links 2-3-4" (German for Left 2-3-4) is a song by Neue Deutsche Härte band Rammstein, released on their third studio album, Mutter (Mother).

The lyrics were written in response to allegations of fascism/nazism directed at the band. In the song, they say "my heart beats to the left, 2-3-4", insinuating they are on the left of the political spectrum. The refrain is an allusion to the revolutionary song , written by Bertolt Brecht for the Communist Party of Germany in the 1930s and re-popularized by Hannes Wader in the German Democratic Republic.

The song uses an alternate pronunciation of the German two, using zwo (pronounced tsvo) rather than zwei (tsvy). "Zwo" is more commonly used within the German military, or in the Austrian dialect, and this song presents a strong, militaristic theme, 'left - two - three - four' being a common drill instructor's chant to keep a marching formation in step.

The music video for the song uses CGI to portray the struggle of an ant-colony against attacking beetles. The ants in the video are doing human-like tasks such as playing football, watching television, and dancing. During the video, the band can be seen playing on a movie theater screen. Also a Rammstein logo can be seen with two crossed hammers which symbolize the Communist proletariat working party. During the movie theater scene the beetles attack, killing many ants. The beetles symbolize Nazism and the ant-colony symbolizes Communism. One ant is seen watching what the monstrous beetles are doing. The same ant then goes underground to rally the other ants and kill the beetles which symbolizes how the Left may crush the Right if they work together. There is also a right hand belonging to a body lying near a grave with a cross on it, covered by ants near the end of the video (symbolizing the defeat of the Right hand parties).
