"We Are One (Ole Ola)" is a song recorded by Cuban American rapper Pitbull for One Love, One Rhythm – The 2014 FIFA World Cup Official Album (2014). It is the official song of the 2014 FIFA World Cup and features guest vocals from American entertainer Jennifer Lopez and Brazilian singer Claudia Leitte. The artists co-wrote the song with Sia, RedOne, Danny Mercer, Dr. Luke, Cirkut, and Thomas Troelsen; the latter three are also the producers. Whilst receiving positive reviews from critics, initially the song received some negative reactions from Brazilians over its lack of Brazilian feeling. To change that, another version was also released and the music changed slightly to fit Afro Brazilian group Olodum's style of drumming - that version being the one that was used in the music video for the song. "We Are One" has experienced commercial success, reaching the top 20 in countries including Austria, France, Germany, Italy, Spain, and World Cup's host country, Brazil. The song went to its peak at no.1 in 3 countries.

On January 22, 2014, FIFA and Sony Music Entertainment announced that "We Are One (Ole Ola)" would serve as the official song of the 2014 FIFA World Cup. At the occasion, Pitbull said, "I'm honored to join Jennifer Lopez and Claudia Leitte at the FIFA World Cup to bring the world together. I truly believe that this great game and the power of music will help unify us because we are best when we are one." Lopez said Pitbull asked her to join the song: "I can't take credit for this. This was one of Pitbull's call-ins. He had this record, and he's like, 'I think this record could be great for the World Cup. He's like, 'Will you do it with me?' And I go, 'Yeah, of course.'" A solo version of the song featuring only Pitbull leaked online on February 2. On April 8, Pitbull tweeted an iTunes Store link to the track, debuting the song.
