Georgi Ivanov Kyoseivanov (Bulgarian: Георги Иванов Кьосеиванов; 19 January 1884 – 27 July 1960) was a Bulgarian politician who was Prime Minister from 1935 until 1940.

Kyoseivanov came to power on 23 November 1935 after a period in which the country had had three Prime Ministers in quick succession.

He went on to become the longest-serving PM since Andrey Lyapchev and throughout the period of his administration he also held the post of Foreign Minister.

[1] The government oversaw the trials of the instigators of the 1934 military coup and also concluded pacts with Yugoslavia and Greece as Nazi Germany undertook a policy of economic isolation of the Balkans.

[3] Despite this Kyoseivanov's government was seen as little more than a puppet of Tsar Boris and, although it lasted until 1940, achieved little other than allowing the Tsar to effectively govern as an absolute monarch.
