The 2021 Chicago Marathon was held on October 10, 2021. It was the 43rd edition of the annual Chicago Marathon, and the first after the start of the COVID-19 pandemic in 2019. The 2020 Chicago Marathon was canceled as a result of the pandemic. The race was the third of five World Marathon Majors scheduled for 2021; all the events in the series took place in the span of six weeks between late September and early November. Participants were required to provide proof of COVID-19 vaccination or a negative COVID-19 test taken within 72 hours of attending the event.
