"Tuya Soy" (in English, "I'm yours") is a song by Puerto Rican recording artist Ivy Queen from her third studio album Diva (2003). It was released in mid-2004, following the releases of "Quiero Bailar", "Quiero Saber", "Papi Te Quiero", and "Guillaera" as the first four singles.

Lyrically, Ivy Queen tells the story of a woman who suspects her husband of cheating. Despite being in rotation on various Anglophone and Hispanophone radio stations in the United States, the song failed to chart in Billboard magazine.

Following the failed commercial success of Ivy Queen's previous two studio albums, En Mi Imperio (1997) and The Original Rude Girl (1998), she was dropped from the Sony label and took a hiatus from her musical career in 1999. The lead single from the latter, "In The Zone", a duet with Haitian singer Wyclef Jean, was a moderate success in the United States in March 1999. The subsequent single "Ritmo Latino" and its parent album, were overlooked by consumers and failed to chart. However, the album was critically acclaimed by many including an editor for Allmusic who awarded the album four out of five stars and listed it as an selected "Allmusic Pick".

In the following years, Queen began appearing on reggaetón compilation albums spawning hits such as "Quiero Bailar" from The Majestic 2 and "Quiero Saber" from Kilates. In 2003, Queen and her then-husband Gran Omar signed with Real Music, an independent record label with headquarters in Miami, Florida and established by Jorge Guadalupe and Anthony Pérez. They appeared on the label's first effort Jams Vol. 1 which Pérez released after several major labels turned him down. She benefited from Pérez producing the "important reggaetón television show" The Roof, which aired on Mun2 and detailed urban music and lifestyle by frequently appearing and performing on the show.
