"Ay Amor" (English: "Oh Love") is a ballad written and performed by Mexican singer-songwriter Ana Gabriel and produced by Mariano Pérez Bautista. It was released as the first single from her third studio album Pecado Original (1987). This song became the second to spend 14 consecutive weeks at number one in the Billboard Hot Latin Tracks chart, after fellow Mexican singer Daniela Romo with "De Mí Enamórate", being surpassed in the same year by Yuri when her single "Qué Te Pasa" achieved sixteen weeks at the top of the chart.

"Ay Amor" is also recognized as one of Gabriel's signature songs and has been performed by several singers, including Tino y su Banda Joven, Jannette Chao, Keyla Caballero and Myriam.

Mexican singer-songwriter Ana Gabriel, after ten years of preparation, received in 1984 the opportunity to participate on the Mexican Festival 'Valores Juveniles', in which she participated as a composer with the song "No Me Lástimes Más", and won second place in the contest. Following this victory she was called by CBS and was offered an exclusive contract. The following year, 1985, Gabriel participated in the OTI Festival with the song "Búscame", wrote with Tony Flores, and took the award for 'Revelation of the Year'. That same year she recorded his first album, entitled Un Estilo. In 1986 she participated again in the OTI with the song "A Tu Lado" and this time was recognized as 'Singer of the Year'. Finally, in 1987, Gabriel had her third chance at this festival with the song "Ay Amor", which earned the awards for Best Song, Best Singer and Best Composer, and the opportunity to represent Mexico at the Festival OTI International in Lisbon, Portugal, where she ranked third, in a tie with Spain.
