"Two of Hearts" is a hit song released in 1986 by American singer Stacey Q. Pop singer Sue Gatlin co-wrote the tune along with John Mitchell and Tim Greene. Although Gatlin did record her own version, Stacey Q released her version first, and it would become the latter's biggest hit.

Musically, "Two of Hearts" is a Hi-NRG song. It utilizes vocal sampling with the repetitive usage of the line "I Need You" in its hook. The lyrics of the song revolve around love and romance. "Two of Hearts" received positive reviews from music critics and was a commercial success. It entered the Billboard Hot 100 chart in mid-June 1986, breaking into the Top 40 in mid-August, and peaking at number three to become one of the highest-selling singles of 1986. "Two of Hearts" was ranked number twenty-seven in VH1's 100 Greatest One Hit Wonders of the '80s.

The accompanying music video was directed by Peter Lippman. It depicts Stacey Q dancing in front of a white background in various outfits and performing at a night club. "Two of Hearts" has been covered by a number of artists and has appeared in feature films such as Nowhere, Little Nicky, Party Monster and Hot Rod (where it was done to punchdance).

After the release of the album Playback (1983) with the band SSQ, Stacey Q began working with Jon St. James on her solo material. St. James brought her the song "Two of Hearts," suggesting that she record it. "Two of Hearts" was a tune St. James had initially produced for Sue Gatlin, who had co-written the song with John Mitchell and Tim Greene, recording her own version. At first, Stacey Q refused to record a song written by someone else, but later she changed her mind and decided to record it.
