Julia Gallego is a renowned Spanish voice actress, recognized for her extensive career in dubbing, particularly for her work on anime series during the 1970s and 1980s. Born Julia Gallego Solórzano on January 31, 1934, in Valladolid, Spain, she was introduced to the world of dubbing at a young age by her father, the noted voice actor Julio Gallego. This early start saw her making her first recordings as a child, standing on a chair to reach the microphone.

Her career background is deeply rooted in the golden age of dubbing in Barcelona, where she and her father often worked together on productions for studios like Metro Goldwyn Mayer. While she initially balanced dubbing with work as a dancer and theater actress, her voice work became her primary focus. She became specialized in voicing young boys and teenage characters, a common practice in dubbing at the time, which made her a prominent figure in many animated series imported to Spain.

Gallego's major voice roles include some of the most iconic characters in anime history. She is widely known for providing the Spanish voice of the protagonist Koji Kabuto in the seminal super robot series Mazinger Z, a role that brought her considerable popularity. Another significant role was that of the young King Arturo in the anime series Entaku no Kishi Monogatari: Moero Arthur. Her film work includes voicing Jim in the animated feature Animal Treasure Island and, much later in her career, the role of Charlotte in the 2017 film Mary and The Witch's Flower. Her other notable credits include Telémaco in the French-Japanese series Ulysses 31, Jimmy in Hello! Sandybell, and a role in Wedding Peach.

Recurring collaborations were a natural part of her career within the close-knit dubbing community in Barcelona. She frequently worked alongside other established voice actors of the era, such as Nuria Mediavilla, Dionisio Macías, and Pepe Mediavilla, on numerous projects for studios like DOVI and VSI-Sonygraf.

Among her notable achievements, Julia Gallego was honored with the Atril de oro award in 1985 for her dubbing work in the film La luna. Her career is remarkable for its longevity and impact, spanning over eight decades and continuing into her later years, which has cemented her status as a legendary figure in Spanish dubbing.
