Santiago Tomás Castro is an Argentine professional footballer known for his strength, determination and goalscoring ability. Born in San Martín, Buenos Aires, on September 18, 2004, the striker developed at Vélez Sarsfield before moving to Italian football with Bologna and later joining AS Roma.
Behind Castro’s rapid rise is a supportive Argentine family with strong connections to football. His father is Darío Castro, his mother works for the Argentine state, and he has a younger brother named Ramiro. In his personal life, Santiago is married to Agustina González, with whom he is expecting his first child.
Who Are Santiago Castro’s Parents?
Santiago Castro was raised by his parents in the province of Buenos Aires. His father is Darío Castro, while his mother’s name has not been widely disclosed by reliable publications. Both parents supported his development from his childhood years at Vélez Sarsfield to his move into European football.
Castro has regularly acknowledged the importance of his family. After helping Vélez avoid relegation in 2023, he explained that he had worked through a challenging period with the support of his relatives and friends. His comments, published by the official Vélez Sarsfield website, showed how closely his family experienced the pressure surrounding the club.
His parents also supported his decision to represent Argentina at youth level. When his transfer to Bologna was being completed during the 2024 South American Olympic qualifying tournament, Castro said that playing for his country was a source of pride for both him and his family.
Who Is Santiago Castro’s Father?
Santiago Castro’s father is Darío Castro. He works in the judicial sector in Argentina and previously played football as a midfielder, although he did not build the same high-profile professional career later achieved by his son.
Darío played for Club Comunicaciones, a football institution based in the Agronomía neighborhood of Buenos Aires. This connection meant that Santiago grew up in a household where football was already an important part of family life.
The relationship between the Castro family and Comunicaciones extends across generations. Santiago’s grandfather also played for the club. During a return to Argentina in 2025, Santiago trained at Comunicaciones and explained that both his father and grandfather had represented the institution. The visit was documented by Página/12.
Although Santiago ultimately developed professionally at Vélez Sarsfield, his father’s experience helped introduce him to the realities of football. Darío understood the patience, discipline and commitment required to progress through an academy before reaching senior level.
Who Is Santiago Castro’s Mother?
Santiago Castro’s mother is an Argentine state employee. Her full name has not been consistently published by established sources, and she appears to prefer a private life away from her son’s growing international profile.
Castro has spoken broadly about the support provided by his entire family without revealing extensive personal information about his mother. She was part of the stable environment that allowed him to enter Vélez’s academy at a young age and continue developing through the club’s youth categories.
When Castro moved from Argentina to Italy in January 2024, the transition involved leaving his parents and other relatives behind. He has frequently dedicated important football moments to the family members he misses while living abroad.
After scoring the goal that sent Bologna into the 2025 Coppa Italia semifinals, Castro said the achievement was for his family. His remarks reflected the emotional importance of maintaining that connection despite the distance between Italy and Argentina.
Does Santiago Castro Have Any Siblings?
Santiago Castro has a younger brother named Ramiro Castro. Santiago shares a close bond with him and has dedicated goals to Ramiro during his football career.
Ramiro has remained outside the public spotlight, and reliable reports do not provide details about his age, education or occupation. There is also no confirmed information indicating that he is pursuing a professional football career.
Santiago’s public gestures toward his younger brother demonstrate the importance of their relationship. However, because Ramiro is a private family member, personal details that have not been voluntarily shared should not be treated as public information.
No additional brothers or sisters have been reliably documented. Ramiro is therefore the only sibling who can presently be identified with confidence.
Who Is Santiago Castro’s Wife?
Santiago Castro’s wife is Agustina González. The couple were already together during his period at Bologna, although they initially kept many details of their relationship private.
Castro publicly thanked his girlfriend after Bologna defeated AC Milan to win the Coppa Italia in May 2025. In comments published by the official Bologna website, he thanked his family, his girlfriend and the wider Bologna community for supporting him during the season.
The couple subsequently formalized their relationship. Italian reports indicate that Santiago and Agustina completed a civil marriage in Italy before holding a wedding celebration in Argentina in 2026. Agustina later publicly supported her husband following his move to Roma.
When Castro joined the Rome club, Agustina shared a message expressing her happiness at accompanying him during the new stage of his career. Although some publications still describe her as his girlfriend or partner, reports about their civil ceremony indicate that wife is the more accurate description.
Does Santiago Castro Have Children?
As of now, Santiago Castro and Agustina González are expecting their first child. The couple announced the pregnancy publicly in August 2026, shortly after the striker began his career with Roma.
Castro and Agustina shared the announcement from the Stadio Olimpico after Roma’s opening Serie A match. They posed with a small Roma shirt carrying Castro’s name and number, symbolizing the future arrival of their baby.
The announcement was reported by the Italian news agency Adnkronos, which confirmed that this will be the couple’s first child. Therefore, Castro does not yet have a publicly confirmed born child, but he is preparing to become a father for the first time.
Some social-media reports have claimed that the baby is a boy. However, the more authoritative coverage of the couple’s announcement did not clearly confirm the child’s sex, so that detail should be treated cautiously unless Santiago or Agustina announces it directly.
How Important Is Family to Santiago Castro?
Family has been a recurring theme throughout Castro’s football journey. He has thanked his relatives after major victories, spoken about missing them while living in Italy and credited them with helping him overcome difficult periods.
His emotional connection to his family was particularly visible during Vélez’s difficult 2023 season. Castro scored important goals as the club fought to remain in Argentina’s top division, later explaining that his parents and friends had helped him cope with the pressure.
His family’s football heritage also gives his career additional meaning. With both his father and grandfather having played for Comunicaciones, Santiago represents the third generation of the family with a significant connection to the sport.
Moving to Europe required him to become independent at a relatively young age, but his comments suggest that his family remained a central source of motivation. His marriage to Agustina and their forthcoming first child now represent a new stage in his family life.
