Vivien Blotzki is a German model and the winner of the 18th season of the casting show Germany's Next Topmodel.

Vivien Blotzki's mother is from Brazil. Blotzki herself comes from Münstermaifeld (Mayen-Koblenz district) and is on the verge of completing her apprenticeship as a retail saleswoman in 2023. She participated in the 18th season of Germany's Next Topmodel in the same year.

In the finale, she emerged victorious over four other finalists, winning the 18th season of the show. As the winner, she received a prize of €100,000 and appeared on the cover of a German edition of Harper's Bazaar. Additionally, she will be the face of a makeup brand's campaign in 2023.

Blotzki became the first plus-size model, meaning she has a larger clothing size than usual, to win the Germany's Next Topmodel competition.
