The 2021
Weltklasse Zürich was an outdoor
track and field meeting in
Zürich, Switzerland. Held on 28–29 August 2021 at the
Letzigrund, it served as the finals of the
2021 Diamond League – the highest level international track and field circuit. It was the first time that Zürich exclusively hosted the Diamond League finals, as the
2020 Diamond League finals were cancelled due to
COVID-19.[1] It was also hailed as the best single-weekend track and field event of
the year 2021.[2]
