Fatherfucker is the third studio album by Canadian singer Peaches, released on September 23, 2003, by XL Recordings.

Cover versions of Electric Six's "Gay Bar" and Berlin's "Sex (I'm a ...)" are included as bonus tracks.

[3] Peaches also toured as part of the 2004 State of Exit festival in Novi Sad, Serbia.

[6] Peaches and Maxx Ginnane directed a promotional video for "Tombstone, Baby" that features Ella Ferrante and Billi Lime dancing with knives and cutting each other's clothing.

Club wrote that "nearly all of Fatherfucker falls back into ostensibly bracing anthems that sound plain stupid in such abundance.

[29] The Village Voice ranked Fatherfucker at number 157 on its Pazz & Jop critics' poll of 2003.

[32] Fatherfucker earned Peaches a nomination for Outstanding Music Artist at the 15th GLAAD Media Awards,[33] but lost out to Rufus Wainwright.
