The 2020 Denmark Open (officially known as the Danisa Denmark Open presented by Victor for sponsorship reasons) was a badminton tournament which took place at the Odense Sports Park in Denmark from 13 to 18 October 2020. It had a total purse of $750,000. Some badminton powerhouse countries such as China, Indonesia, South Korea, Malaysia, and Thailand did not send their representatives to the event in the light of the COVID 19 pandemic, causing a less competitive event in which most top players did not participate. Some Japanese players, including Kento Momota, did not participate as well.
