First Mayor of the city-state of Hamburg

The following is a chronological list of mayors of Hamburg, a city-state in Germany. The mayors are the head of the city-state, part of the government of Hamburg. Since 1861 according to the constitution of 28 September 1860 the state has been governed by the ten-member Senate, which had been called council (in the German language of that time: Rath) before that time. It is headed by the First Mayor of Hamburg (German title: Erster Bürgermeister der Freien und Hansestadt Hamburg) as the President of the Senate. His deputy is the Second Mayor.

As Hamburg for much of its history was a free imperial city and later a sovereign state, the position of First Mayor historically was equivalent to that of a sovereign head of state. In the 1871–1918 German Empire, the Hamburg First Mayor was equivalent to the federal princes of the 23 German monarchies (4 of whom holding the title King and the others holding titles such as Grand Duke, Duke or Sovereign Prince).

Prior to World War I the two mayors were elected for one-year-terms. Until 1997 the First Mayor was primus inter pares among his colleagues in the Senate, by whom he was elected. Since then, he has been elected by the Hamburg Parliament (German: Hamburgische Bürgerschaft) and been able to appoint and dismiss other Senators.

The function of burgomaster (mayor) was usually held simultaneously by three persons, serving as an executive college. One of the three being burgomaster in chief for a year, the second being the prior burgomaster in chief, the third being the upcoming one. Therefore, sometimes up to three names are mentioned for one year, since the names of the three appear in deeds, signed with or mentioning their names. The names in the list from 1239 until 1820 were archived in a book by Johann August Meister (1820). This is an incomplete list of burgomasters and uses the spelling in Meister's book, which is preserved in the Hamburg state library. After 1820 the list were added by hand. On 6 August 1806 Hamburg gained sovereignty as an independent country. From 1811 to 1814 Hamburg was part of France in the Bouches-de-l'Elbe.
