90 Millas (90 Miles in English, pronounced "no-VEN-ta Mi-yas" in Spanish) is the eleventh solo studio album by the Cuban-American singer-songwriter Gloria Estefan, and her fourth Spanish language album, coming after Mi Tierra, Abriendo Puertas and Alma Caribeña.

[2] Carlos Santana made a guest appearance on the album, which also included several other legends of traditional Latin music such as: Andy García, Jose Feliciano, Cachao, La India, Candido Camero, Sheila E., Johnny Pacheco, Papo Lucca, Sal Cuevas, Giovanni Hidalgo, Arturo Sandoval, Paquito D'Rivera, Nelson Gonzalez, Alfredo "Chocolate" Armenteros, Generoso Jiménez, Luis Enrique, and Orestes Vilato.

The album was released worldwide in September 2007 and the track listing was different in certain countries, the European version and the Limited Edition Package (which was released exclusively in United States and United Kingdom) have two bonus tracks; "Vueltas Da La Vida" and "No Llores" (featuring Wisin & Yandel).

The Japanese edition also features "Vueltas Da la Vida" as well as "Al Verte Partir", a track exclusive to this version.

Estefan also received three nominations at the Latin Grammy Awards of 2008, and won for "Best Traditional Tropical Album" and "Best Tropical Song" for "Píntame De Colores" (she was also nominated for "Best Music Video – Long Form", but she lost out to Julieta Venegas's MTV Unplugged video concert).

Estefan was also selected as the "Persona Del Año" ("Person of the Year"), the first time this award was given to a female artist.

The performance was free and open to members of the public, and was part of the "Wereld Havens Dagen" (World Harbour Days), commemorating the 75th Anniversary of the Port of Rotterdam.

The "90 Millas World Tour" was made to promote the album only on the European continent,[9] but before she started the European tour, Estefan made an appearance in the United States at the opening of the MGM Grand's new venue, the Foxwoods Resort Casino, for three sold-out dates including Memorial Day.

The song received some praise by Leila Cobo of Billboard who called it "a standout for impeccable production and enviable mix that allows every instrumental line (and there are many) to resonate with bell-like clarity.

[11] Jason Birchmeier from Billboard commented that "ever since Gloria Estefan split from Miami Sound Machine in 1989 to go solo, her best efforts tended to be her Spanish-language ones, and her fourth such album, 90 Millas, is no exception.

[12] Tijana Illich from about.com said "Gloria Estefan's fourth Spanish-language album is her best, not surprising when you consider the spectacular cast of musicians that join her on this homage to her native Cuba.

90 Millas takes Estefan back to her roots with lots of varied Afro-Cuban rhythms and genres, some pure in form, others mixed with her trademark pop sound.
