Gold: 100 meter butterfly, Rio de Janeiro 2016.
Her career's so far biggest win. Sjöström became the first Swedish female swimmer to win Olympic Games gold and she was in monster form, broke the world record and outclassed the competitors.
Silver: 50 meter freestyle, Tokyo 2021.
Perhaps her biggest achievement considering the elbow fracture just five months earlier. Against all odds, she could still snatch an Olympic Games medal.
Silver: 200 meter freestyle, Rio 2016.
Sjöström had to give in to the star duel against Katie Ledecky, USA. It was only 35 hundredths of a second since the stars had fought out one of the "giants' battles" and pushed each other to the limit.
Bronze: 100 meter freestyle, Rio 2016.
The third medal in Rio was a bronze. Simone Manuel, USA, and Penny Oleksiak, Canada, shared the gold, Sjöström was 29 hundredths behind the winning duo.
