"Estoy Enamorado" (English: I'm in Love) is a song originally recorded in Spanish by the Cuban-Colombian duo Donato & Estefano for their 1995 Mar y Adentro album.

Both the original song and its "Estou Apaixonado" version were major hits in Brazil, having been extensively played as a romantic theme for TV Globo's 1995-1996 prime-time telenovela "Explode Coração".

In 1996, the sertanejo duo João Paulo & Daniel released the album João Paulo & Daniel Vol. 7. The CD brought "Estou Apaixonado" in Brazilian Portuguese, becoming the duo's most successful hit, and rendering it a double platinum certification for more than 500 thousand copies sold.

In 2009, Mexican singer Thalía released a version of the song in her live album Primera fila, featuring Puerto Rican musician Pedro Capó. "Estoy Enamorado" was released as third official single in the United States, Mexico, and Puerto Rico, while in Argentina, Spain, and Europe, it was released as "Enséñame a vivir".

In 2013, Thalía released an eponymous Portuguese-language album, and Daniel joined her for a relaunch of his "Estou Apaixonado" version. The song served as the lead single for this album and topped the Mexican singles charts, making it Thalía's third consecutive hit in her country, but had moderate airplay success in Brazil. This version was also included in Daniel's 2014 EP 30 Anos - O Musical.
