"I Hate Boys" is a song recorded by American recording artist Christina Aguilera for her sixth studio album, Bionic (2010). The song was written by Aguilera, Ester Dean, William Tyler, Bill Wellings, J. J. Hunter and Jamal Jones, who also handled the production of the track. "I Hate Boys" is a glam rock and pop song, containing elements of urban pop and synthpop. Lyrically, it is a hate-driven song about ridiculing bad boys.

"I Hate Boys" was released as the second and final single from Bionic in New Zealand and Australia. It was serviced to Australian radio on June 28, 2010, and released as a digital single in Australia and New Zealand on September 3. The song received mixed to favorable response from music critics; some of them called it a "girl anthem", but others felt it has too adolescent lyrics and called it a "filler". Upon the release of Bionic, "I Hate Boys" debuted at number 51 on the Gaon International Singles Chart during the week of June 6, 2010.

Initially, "I Hate Boys" was supposed to be produced by Le Tigre. Group member Johanna Fateman wrote about working with Aguilera on their official website:

"… While the giant sound of her stacked vocals and the pop sheen she lends to the tracks might seem at odds with Le Tigre's aesthetic roots, it really works. The songs have a lot of elements we're known for, like a garage guitar sound, schoolyard chants, new wave-y synths, electro beats, and somehow it all sounds crazily right with Christina's unbelievable voice."

However, it was later revealed that the song was produced by Polow da Don and that Le Tigre only produced the song "My Girls". Polow da Don talked about working with Aguilera in a Billboard interview, stating: "There's two things you need to know about Christina Aguilera: The first is that, as far as her singing goes, she's a professionally trained animal. And the other is that she knows exactly, absolutely what she wants."
