The Gothenburg quadricentennial jubilee (Swedish: Göteborg 2021) was originally scheduled to be held in Gothenburg, Sweden, in 2021 to celebrate the 400th anniversary of the city. Due to the ongoing COVID-19 pandemic in Sweden, organizers have postponed the celebrations to 2023, while a small-scale event will still take place in 2021. The anniversary follows the city's tricentennial jubilee held in 1923 (which was intended to be held in 1921, but was delayed due to World War I). The city was granted its founding royal charter in 1621, by King Gustavus Adolphus.
