Mary Jane Cruz-Mendoza (Tagalog pronunciation: [ˈkɾus mɛnˈdɔsɐ]; born August 29, 1966), known professionally as Jamie Rivera (Tagalog: [ˈdʒeɪmɪ ɾɪˈbɛɾa]), is a pop singer from the Philippines and also known as the Inspirational Diva.

From her post-EDSA Revolution debut album Hey It's Me under PolyEast Records, Rivera has had five gold and two platinum-selling albums issued by PARI. Since 1996, her albums were released by Star Music, a recording company owned by the Philippine media company ABS-CBN Corporation. Rivera has sung to Pope John Paul II, and played the role of Kim in the Miss Saigon musical at the Theatre Royal, Drury Lane, in the West End of London, England. Most recently, she is known for singing the theme song of the Papal Visit 2015 We Are All God's Children. She also met Pope Francis during his Apostolic visit to the Philippines on January 15–19, 2015.

Rivera is a Roman Catholic. She is married to JB Mendoza and has a daughter named Reine Mendoza, who was born on December 12, 1996.

She graduated from University of Santo Tomas with a degree in Economics.

In August 2003, Jamie was accused for incorrect lyrics involving one of her songs, "My Life In Your Hands" from her 2001 album, Seasons. The song was composed by Kathy Troccoli and Bill Montvilo, and originally performed by Troccoli on her self-titled album in 1994. In Jamie's version of that song, the lyrics were eventually changed, including the words "People" replacing "Keeping" and "Love" replaces "Hope" in the chorus, and the word "Stone" replacing "Lord" in the coda. In addition, Careers-BMG Music Publishing (the song was published by Emily Boothe, Inc., a Reunion Music Group division, in 1993; BMG Music acquired Reunion outright in 1995, and was subsequently acquired by Universal Music Publishing Group in 2007, now known as Universal Music-Careers) and Floating Note Music, publishers of that song, had not granted a master licence for inclusion of the song in the album released by her label, Star Music.

In addition, they eventually misspelled the composers' names in the album's liner notes. Narciso Chan, the sales and marketing director of BMG Pilipinas (now Sony Music Philippines), the Philippine arm of BMG Music Publishing, says that the incorrect lyrics, the misspelling of the song's composers and uncrediting of the publishers of the song "My Life In Your Hands" is 'blatantly illegal' under the United States copyright laws as the song was protected under a United States copyright, as the copyright was held at BMG's Nashville office. Nixon Sy, Star Music's assistant marketing director, did not receive the letter from Mr. Chan and the company had declined to comment. After negotiations with BMG Music in both Manila and Nashville along with Mr. Montvilo's publisher Floating Note Music in New York, Star Music's VP for operations Annabelle Regaldo, managing director Enrico Santos and marketing director Heinrich Ngo said that her album Seasons will be reissued with correct lyrics of the song "My Life In Your Hands" in October 2003, with the correction of the song composers' names and inclusion of the publisher's credits in the album's liner notes, as well as three additional tracks for the 2003 re-release of the album.
