"The Rat" is a song by American indie rock band the Walkmen. It was released as the first single from their second studio album, Bows + Arrows (2004), on April 19, 2004. The song peaked at number 45 on the UK Singles Chart.

Singer Hamilton Leithauser said the song originated in a jam session when the band were "just screwin' around." The band's drummer Matt Barrick instigated the track by playing a fast drum pattern. The band then quickly built this foundation into the full track, Leithauser said "we threw some chords on it, I wrote the words in five minutes." The song had been included in the band's live sets as early as February 2002, with slightly different lyrics than the recorded version.^[1]

The band's usual method was to self-produce their material. However, after unsuccessful attempts to record the layered electric organ and guitar, they decided to record the track with a professional record producer at the advice of their label. This was later viewed as an unsatisfactory move by bassist Walter Martin who said "It doesn't sound right at all. I think the production for the rest of the album makes the music sound big and live. But it just sounds dense and solid."^[2]

Ezra Koenig, who worked as an intern for the band, says the song was originally titled "Girls At Night" and was recorded a year after it was first played to him.^[3]

The video features a live performance shot in black and white making use of chiaroscuro and directed by filmmaker Eva Aridjis.

The track has received highly positive critical acclaim, featuring in many end-of-decade lists. It was named thirteenth best track of the decade by NME^[4] and 20th best track of the 2000s by Pitchfork Media who named it "a St. Valentine's Day Massacre of relentless drums, bass, and guitar."^[5] Rolling Stone called it "one of the greatest songs of the century".^[1] Modern Drummer magazine praised Barrick's performance as "a jaw-dropping exercise in precision and velocity".^[6] In October 2011, NME placed it at number 31 on its list "150 Best Tracks of the Past 15 Years".^[7]

Stylus Magazine took a different slant saying that the song's 'one-hit wonder' success "was the worst thing to ever happen to The Walkmen. It brought the iPod-lazy—singles, MP3s, mix and matchers—to their shows and records."^[8]

The song is featured on the soundtracks of Major League Baseball 2K7, Dirt 2, and True Crime: New York City.
