Felix Teodor Hamrin (14 January 1875 – 27 November 1937) was a Swedish politician.

He was the leader of the liberal Freeminded People's Party and served as Prime Minister of Sweden from August to September 1932.

When Ekman was forced to resign shortly before the elections in 1932 due to the Kreuger crash, Hamrin became prime minister.

His term of office was only 50 days, giving him the record for serving the shortest amount of time as prime minister of Sweden.
