"Emotions" is a song by American singer and songwriter Mariah Carey. It was written and produced by Carey, David Cole and Robert Clivillés of the C+C Music Factory, and recorded for Carey's second album of the same name (1991). It was released as the album's first single on August 13, 1991 by Columbia Records. The disco song has its protagonist going through a variety of emotions, from high to low, up to the point where she declares "you got me feeling emotions". Musically, it was borrowed heavily from 1970s disco, and flaunted Carey's upper range and extensive use of the whistle register.

Carey was sent to work with the C+C Music Factory and they composed the song "You're So Cold", which became the first choice for the album's first single. However, a second session with the production team had them feeling in a lighter mood when "Emotions" was created and finally decided upon as the lead single.

"Emotions" is a disco song and it is written in the key of C major. Carey usually prefers to transpose the key to B♭ major when performing live (one example of this is on MTV Unplugged). Carey's vocal range spans more than four octaves on the track, from C₃ to E₇. The song tested and challenged Carey's vocal range and is her first song to require the execution of multiple whistle notes. The sheet music of the song has a 8va marking on the last part of the song.

The single's music video, directed by Jeff Preiss, features Carey and friends with exotic animals experiencing emotions while partying and having fun around town in New York City. The video was desaturated but still maintains various color tints, which change from brown to red to blue and so forth.
