Alexander Skarsgård Siblings: Alexander Skarsgård stands out as one of Hollywood’s most magnetic Swedish exports, known for roles that range from the vampire Eric Northman to the calculating tech mogul in Succession. Behind the tall frame and quiet intensity sits a large, tightly knit family that has quietly become one of the most productive acting dynasties of the past two decades. Born on August 25, 1976, in Stockholm, Alexander is the eldest of eight children fathered by the acclaimed actor Stellan Skarsgård. Six share the same mother, physician My Skarsgård; two are half-brothers from Stellan’s second marriage.
Here is a clear, up-to-date look at every sibling.

Stellan later married producer Megan Everett and welcomed two more sons: Ossian (2009) and Kolbjörn (2012). That brings the total to eight.

The Acting Brothers Who Followed the Family Path
Gustaf, the second-oldest, began acting as a child and later trained at Sweden’s top drama school. His portrayal of the eccentric shipbuilder Floki across six seasons of Vikings made him a cult favorite. He has since appeared in Westworld, Cursed, and Christopher Nolan’s Oppenheimer.
Bill Skarsgård arrived more than a decade later and quickly carved his own lane in horror and dark drama. His transformation into Pennywise the Clown in the It films remains one of the most talked-about performances of the late 2010s. He has continued with intense roles in John Wick: Chapter 4, Barbarian, and Nosferatu.
Valter, the youngest of the full siblings, has steadily built a career in both Swedish cinema and international projects, including Lords of Chaos and several Nordic thrillers. The three acting brothers, together with Alexander, regularly appear in each other’s support systems and occasionally cross paths at premieres.
The Siblings Who Chose Different Roads
Not every Skarsgård followed Stellan into the spotlight. Sam trained as a physician and works in intensive care. Alexander and Bill have both spoken publicly about their respect for him, describing their brother as the one who “saves lives on a daily basis.”
Eija, the only sister, spent years modeling before moving into casting. She has contributed to Swedish productions such as Young Royals. Family members have noted that she has always held her own among the brothers and values her place as the sole daughter.
Half-Brothers and the Next Generation
Ossian and Kolbjörn are still young but have already begun appearing in small roles, continuing the family’s natural pull toward the screen. The entire group remains close. When Alexander is home in Stockholm, the siblings often live within a few blocks of one another and gather frequently.
Conclusion
Alexander Skarsgård’s siblings form a remarkable mix of high-profile talent and quiet professionalism. Four full brothers and two half-brothers pursue acting careers at different levels of visibility, while Sam and Eija have built respected lives outside the public eye. The result is a family that feels both larger-than-life and surprisingly grounded. Whether you first discovered Alexander through True Blood, Big Little Lies, or Succession, knowing the full Skarsgård lineup adds depth to the story of one of Sweden’s most successful modern acting clans.
