"Happiness" is the debut single by American recording artist Alexis Jordan. It is the lead single from her self-titled debut studio album, released in the United States on September 7, 2010. The upbeat dance-pop and house rhythm behind the track was heavily sampled from electronic artist Deadmau5's "Brazil (2nd Edit)" (released two years prior to "Happiness"). The lyrics were written by Autumn Rowe, Petr Brdičko, and the track was re-edited for the lyrics by StarGate.

"Happiness" was generally well received by many critics, with some complimenting Jordan's vocal abilities. In the United States, the song topped the Hot Dance Club Songs chart, giving Jordan her first number one on the chart. It reached number 1 in the charts in the Netherlands (staying there for 10 weeks) and has also charted in the top five in countries such as the United Kingdom and Australia. An accompanying music video, directed by Aggressive sees Jordan being torn apart from her love interest. It was noted for its similarities to Kylie Minogue's "Can't Get You Out of My Head".

After being eliminated from the first season of America's Got Talent in 2006, Jordan began posting videos of herself singing cover songs on YouTube, of which she later became a viral sensation for. After receiving a phone call from Stargate, Jordan flew over to New York City to record a few songs with them. It was then announced in the press in March 2010 that she had signed to StarRoc/Roc Nation after Jay-Z had noticed her in the studio with Stargate.
