"I Wanna" is a song by American rock band the All-American Rejects, released as the third and final single from their third studio album When the World Comes Down on June 8, 2009.

"I Wanna" was written by Nick Wheeler and Tyson Ritter in Florida, United States and was one of the first songs to be written and recorded for When the World Comes Down within a six-month time period both in the studio and the band's tour bus and was refined by Ritter numerous times before recording began.

Sputnikmusic were more negative, stating "'I Wanna' has enough cringe-inducing lyrics to fill a Mariah Carey song and Ritter’s delivery is bored, at best.

A music video for "I Wanna" was directed by Rich Lee and was shot in June 2009 and was released a month later in mid-July.

Towards the end, the All-American Rejects are seen performing in front of their party guests with Ritter and the ex-girlfriend crowd surfing towards each other in the audience and ultimately renewing their relationship when they reach each other.
