"Obsesión" is a song by Dominican-American bachata band Aventura. It was included on the 2002 album We Broke the Rules. It achieved huge success in many countries, topping many international charts. In France, the song held the country's number one slot for seven weeks and as of August 2014, it was the 19th best-selling single of the 21st century in France, with 565,000 units sold.

In 2004, the song was covered by 3rd Wish, featuring Baby Bash produced by Mintman, but this version was less successful than the original version (number 7 In Switzerland, number 2 in Austria, number 12 in France).

Later, in 2005, the song was covered by Los Horóscopos de Durango in their album Y Seguimos con Duranguense.

Mexican American singer Frankie J made an English and more soul-styled version of the song, featuring Baby Bash, which was called "Obsession (No Es Amor)". This version, although not having success in Latin America and Europe, was successful in the U.S., even reaching number three on the Billboard Hot 100 chart.

The lyrics were written by Romeo Santos, and the refrain is performed by the female vocalist Judy Santos (no relation). The song's lyrics explain a man's liking of a woman to the point of obsession. However, this feeling is "not love", and is still only and just an obsession.

In 2005, Mexican American singer Frankie J covered the song under the title "Obsession (No Es Amor)", featuring Baby Bash. The single peaked at number 3 on the Billboard Hot 100. The song was produced by Dominican record producer Nely "El Arma Secreta". Model Vida Guerra made a cameo in the video as his love interest and object of his obsession.
