Like Onieva, these stars rose through Antena 3, Netflix Spain, and Bambú Producciones dramas and have strong international followings.

Early Life & Education

Alejandra Onieva Molas was born on June 1, 1992, in Madrid, Spain. She grew up in a close, upper-middle-class family in the Spanish capital alongside her older brother Íñigo Onieva and her sister Gloria Onieva. Her mother, Carolina Molas, has often been mentioned in Spanish press, while her father has kept a low public profile.

From childhood, Alejandra showed a clear interest in performance. She took dance classes, participated in school plays, and loved classic Spanish and American films. Teachers described her as outgoing, disciplined, and creative. Unlike many child stars, she did not start on camera early. Instead, she focused on training first.

After high school in Madrid, Onieva began university studies in Advertising and Public Relations. At the same time, she enrolled in professional acting schools to study interpretation, voice, and movement. She trained in textual interpretation and contemporary dance, which later helped her with period dramas that required strong body language and posture.

Her big break came while she was still studying. She auditioned for Antena 3’s daily period series El secreto de Puente Viejo and won the role of Soledad Castro. She left her advertising degree to work full-time as an actress, a decision that changed her career path completely.

Career Journey and Recent Activity in 2026

Alejandra Onieva’s career spans more than 14 years, from daily Spanish television to global Netflix exposure. Her age, now 34 as of 2026, reflects a mature phase where she balances leading TV roles, film work, and fashion partnerships.

Beginnings: El secreto de Puente Viejo (2011 – 2014)

Onieva made her television debut in 2011 as Soledad Castro Montenegro in El secreto de Puente Viejo. The Antena 3 telenovela was a major afternoon hit in Spain and later found audiences in Italy and Latin America. As Soledad, the rebellious daughter of Pepa and Tristán, she appeared in more than 500 episodes.

The role made her a familiar face across Spain. It also taught her how to handle long shooting schedules, emotional storylines, and live audience expectations. By 2014, she left the series to avoid typecasting and to try film and prime-time television.

Film Debut and Prime-Time Transition (2014 – 2018)

In 2014, she made her film debut in Por un puñado de besos (For a Handful of Kisses) alongside Ana de Armas and Martiño Rivas. She played Sol, a supporting role that introduced her to cinema audiences.

She then moved into youth and prime-time series:

• Yo quisiera (2015): Played Natalia in this Divinity musical youth series.
• La sonata del silencio (2016): Played Elena in the TVE period drama based on Paloma Sánchez-Garnica’s novel.
• Ella es tu padre (2017): Played Chloe in the Telecinco comedy series.
• Presunto culpable (2018): Played Amaia Aguirre in the Antena 3 thriller, which helped her shift to suspense roles.

During this period, critics praised her ability to move from romantic drama to comedy and thriller without losing natural screen presence.

International Breakthrough: High Seas – Alta Mar (2019 – 2020)

Her biggest international success came with Netflix’s Alta Mar (High Seas), produced by Bambú Producciones. Set in the 1940s aboard a luxury ocean liner, the mystery series starred Ivana Baquero, Jon Kortajarena, and Alejandra Onieva as Carolina Villanueva.

Carolina, elegant and strong-willed, became a fan favorite. The show ran for three seasons from 2019 to 2020 and streamed in more than 190 countries. For Onieva, it meant global recognition, press tours, and a sharp rise in Instagram followers. Her height, classic style, and period look fit the 1940s aesthetic perfectly, and fashion magazines in Spain featured her widely.

Recent Work From 2021 to 2026

After High Seas, Onieva chose a mix of streaming, network TV, and film:

• Historias para no dormir – Freddy (2021): Appeared in the reboot of the classic Spanish horror series.
• Desaparecidos and stage readings: Took part in guest roles and theater workshops to sharpen her craft.
• Film and short projects: Worked on independent Spanish films and fashion films, including collaborations with Madrid-based designers.
• Brand work: Became a regular at Madrid Fashion Week and fronted beauty and jewelry campaigns.

By early 2026, Spanish entertainment press reported that Onieva was reading scripts for a new period thriller and a contemporary romantic drama. As of September 2026, she has not announced a permanent return to a daily series, preferring limited series and film roles that allow more preparation time. She also remains active in fashion, attending events in Madrid, Milan, and Paris in 2025 and 2026.
