Ella Halvarsson (born 22 October 1999) is a Swedish biathlete who has competed in the Biathlon World Cup since 2023.

[1] Halvarsson gained her first international experience in biathlon at the 2018 Youth World Championships, where she immediately won the gold medal in the relay alongside Amanda Lundström and Elvira Öberg.

During the 2022/23 season, she competed in all stages of the IBU Cup, achieving top-10 results in Pokljuka, Osrblie, and Obertilliach.

Her best performance came in the final race of the season in Canmore, where she hit all her targets in the pursuit, recovered nearly two minutes and climbed 17 places to secure her first podium finish at the senior level.

When Stina Nilsson withdrew due to illness, Halvarsson had the chance to compete at her home World Cup in Östersund.
