"Mann gegen Mann" (German: [ˈman ɡeːɡn̩ ˈman]; "Man Against Man") is a song by the German Neue Deutsche Härte band Rammstein, released in March 2006 as the third and final single from the band's fifth studio album, Rosenrot. The song's narrative portrays a man with strong homosexual desires, and it is the first Rammstein music video to feature nudity since the video for their cover of Depeche Mode's "Stripped".

The text, which deals with the subject of homosexuality in terms of content, remains largely ambiguous in its message, dealing with both homophilia and homophobia. This is quite intentional, as Paul Landers and Oliver Riedel explained in an interview:

We definitely didn't intend to write a gay anthem. Of course it is a critical topic how a heterosexual person deals with the topic of a homosexual person. Maybe we can contribute to defusing the word 'gay' a bit and relativise the negative touch.

— Oliver Riedel

This ambiguity is achieved through artificial elements consisting of complex but open-ended linguistic images and allusions, for example: Ich nehm mein Schicksal in die Hand/Mein Verlangen ist bemannt ("I take my fate into my own hands/My desire is manned") or In meiner Kette fehlt kein Glied/Wenn die Lust von hinten zieht ("In my chain no link is missing/When lust pulls from behind"). In the further lyrics of the song, homophobia is also made an issue several times. Negative views of homosexuality are also presented in three two-liners: Mein Geschlecht schimpft mich Verräter/Ich bin der Alptraum aller Väter ("My gender calls me traitor/I am the nightmare of all fathers"). In between, the negatively connoted German exclamation Schwule! ("Gays!") also occurs.

In the process, the first four stanzas create a quasi-homosexual utopia with partly subtle but also relatively clear allusions. Thus in Trag ich den kleinen Prinz im Sinn / Ein König ohne Königin ("I keep the Little Prince in mind / A king without a queen"), "little prince" is a symbol for the penis, but also for the object of desire in contrast to the queen. At the same time, it is an allusion to The Little Prince (1943), a novella written by the French writer and aviator Antoine de Saint-Exupéry. Rammstein singer Till Lindemann uses a deliberately soft singing style that differs from his otherwise masculine singing voice. The chorus, which is much more expressive and aggressive, uses everyday language, including the phrase Gleich und gleich gesellt sich gern ("Birds of a feather flock together").

Christian Diemer, musicologist and Germanist, subjected both the music video and the lyrics to a deeper hermeneutic examination, and came to the following conclusion:

The text-based findings indicate that contrary expressions of opinion of varying degrees of explicitness and diffuseness are staged, partly in clearly assigned textual elements, partly on the micro-level of ambiguity and metaphors. [...] There are widely varying degrees of concreteness and diffuseness on the one hand and of affirmation and rejection on the other.
