Julie Pearl Apostol Postigo (21 May 1968 – 6 May 1985), better known by her stage name Julie Vega (Tagalog: [ˈdʒulɪ ˈbɛga]), was a Filipino actress, singer and commercial model. She remains very popular in her native Philippines, years after her death at the peak of her career at age 16. She won two FAMAS Awards for Best Child Actress during her brief showbiz career.

Julie Vega was born as Julie Pearl Apostol Postigo on 21 May 1968 at the University of the East Ramon Magsaysay Memorial Medical Center (UERRMMC) in Quezon City, Philippines to a practicing Roman Catholic family and was the youngest and only daughter of six children of dentists Julio Postigo (1931–1991) from Zamboanga del Sur and Perla Apostol (1932–2023) from Iligan City. Her family nicknamed her Darling and Tata, which was given to her by her nanny Flor Argawanon and means "youngest child" in the Visayan language.

Vega was discovered by film and stage director Lamberto Avellana and actress Boots Anson-Roa in 1975 while performing at a Christmas party at the Quezon Institute where her mother then worked, thus starting her career the following year at the age of six as a commercial model in television for Purefoods and Band-Aid. She first used the screen name Darling Postigo and appeared in her first film entitled Ang Pag-ibig Ko’y Huwag Mong Sukatin (You Don't Measure My Love) as the young daughter of the characters played by Anson-Roa and Dante Rivero. It was not until she appeared in her first major lead and breakthrough role in the 1978 film Mga Mata ni Angelita (Angelita's Eyes) that she started using the screen name Julie Vega upon the recommendation of film producer and director Larry Santiago, who owned Larry Santiago Productions which produced the film. She had been chosen to play the title role despite placing only third among over 200 applicants for the role.

Although Vega later had to turn down the title role of Flor de Luna due to her schedule with acting and school, she would finally have her own soap opera when she was cast as the title character in GMA Network’s Anna Liza. Her portrayal of the sensitive, sad-sack and frequently oppressed title character drew the sympathy and affections of the Filipino viewing public and further solidified her star status. The success of Anna Liza made her the chief soap opera rival of Janice de Belen, a fellow child star who also enjoyed success with Flor de Luna, the title role Vega previously turned down, as the two dramas rivaled each other for the attention of the television-viewing public. Yet despite being rivals, the two were best friends in real life. De Belen once mentioned, "There could be no me if Julie accepted the role as Flor de Luna."

Aside from her work in Anna Liza, Vega also starred in several films and won two FAMAS acting awards overall. She won Best Child Actress for Mga Mata ni Angelita and Durugin si Totoy Bato and was nominated for Best Child Actress for Mga Basang Sisiw and Best Supporting Actress for Isang Bala Ka Lang! (You're Just a Bullet Away!).

When Vega became a teenager, she was signed to Regal Films by producer Lily Monteverde, who also owned the film company since its inception in 1962. She was then included among the so-called Regal "Cry Babies" along with then fellow teenaged actresses De Belen, Maricel Soriano, and Snooky Serna. She did a total of six films for Regal, including Where Love Has Gone, Mother Dear, To Mama with Love, and Daddy's Little Darlings, all of which became certified box office hits.

Aside from acting, Vega also became a successful singer in her own right. She initially refused to pursue a singing career of her own, but after repeated prodding from her older brother Joey, who noticed her beautiful singing voice, she finally consented to doing so. She took formal voice lessons under renowned songwriter Cecille Azarcon to further hone her singing voice. With the training she received, she was able to sing many of the theme songs of the movies she appeared in like Dear Mama, Where Love Has Gone, Don't Cry for Me Papa and Iiyak Ka Rin.

It was during one of her singing promotions for Where Love Has Gone that Vega was discovered by Bong Carrion, who then offered her to be a recording artist for the then newly formed Emerald Recording Company owned by Carreon and his then wife, the famous Filipina singer Imelda Papin. Her debut single Somewhere in My Past, composed by Mon Del Rosario, was a major hit which became a certified gold record in only its first few weeks of release and would prove to be her most enduring hit and the one song she would be most identified with. The single's success prompted Bong Carreon and Imelda Papin to launch Vega as a full-time solo artist by coming up with the latter's 1985 debut album First Love, which included Somewhere in My Past and produced her further hit songs like Someone Special, The Memory Will Remain, and the eponymous title track itself.
