Hamburg residents have voted against a future Olympic bid for the northern German city in a referendum on Sunday.
With results still being counted, the state electoral chief Oliver Rudolf said a majority of participants opposed the bid to stage the 2036, 2040 or 2044 Summer Olympics in Hamburg.
Around 1.3 million people from the age of 16 were eligible to vote, with turnout at 49.5%.
Hamburg was competing with Munich, Berlin and a Cologne-led Rhine-Ruhr region bid to become the German candidate.
The decision on who will bid and for which year will be made by the German Olympic Sports Confederation on September 26, but Sunday's vote officially takes Hamburg out of the running.
Munich's bid was backed by a 66.4% majority in a referendum and Cologne/Rhine-Ruhr by 66%. In Berlin, the local parliament approved the bid.
In 2015, Hamburg's plan to bid for the 2024 Olympics was also stopped in a referendum.
Supporters of the latest effort highlighted the use of existing venues, an expected profit and an important boost for the city's infrastructure. Critics pointed out uncertainties about costs, arguing the money should be spent for more pressing projects.
The unofficial final result is expected by 10 pm (2000 GMT).
Germany hosted summer Olympics in Berlin in 1936 and in Munich in 1972.
