Khalifa bin Salman Al Khalifa, Bahraini politician, Prime Minister of Bahrain
Khalifa bin Salman Al Khalifa (Arabic: خليفة بن سلمان آل خليفة) (24 November 1935 – 11 November 2020) was a Bahraini royal and politician who served as the Prime Minister of Bahrain from 10 January 1970 until his death in 2020. He took office over a year before Bahrain's independence on 15 August 1971. He was the longest-serving Prime Minister in the world. Under the 2002 Constitution he lost some of his powers, with the King now having the authority to appoint and (along with the Bahraini parliament) dismiss ministers.

Prince Khalifa was also the paternal uncle of the reigning King Hamad bin Isa Al Khalifa and grand-uncle of the Crown Prince Salman, since he was the younger brother of the previous Emir Isa bin Salman Al Khalifa.
