"I'm That Chick" is a song by American singer-songwriter Mariah Carey, included as a track on her eleventh studio album, E=MC² (2008). Written by Carey, Mikkel S. Eriksen, Tor E. Hermansen, Johntá Austin, Rod Temperton, and produced by the former three, the song draws influence from soul, pop and disco music genres. "I'm That Chick" features a strong bass-line, and heavy disco-flavored production, and incorporates a sample of Michael Jackson's "Off the Wall". The song's lyrics finds the protagonist describing a relationship with their lover, as well as all the good qualities they can offer him. Additionally, the song features Carey wooing her significant other with a positive description of herself, while repeating 'I'm that chick you like'.
At the time of the album's release, "I'm That Chick" was met with acclaim from music critics, and was considered one of the album's highlights. Several reviews complimented the song's strong disco-driven melody and sample, while others concentrated on Carey's lyrics. The song charted due to strong digital downloads in the United States during the debut week of E=MC², and as a result, peaked at number 82 on the Billboard Hot R&B/Hip-Hop Songs chart. Though not released commercially as a single, Carey performed the song live a select number of times, notably on Good Morning America, as part of a three-piece outdoor concert, the 2008 Fashion Rocks ceremony, the The Hills season premiere party, and Canadian Idol.
