Led By Donkeys is a British political campaign group, established in December 2018 as an anti-Brexit group, but which has also criticised other actions of the Conservative government. Since the group's creation its four founders have been calling out what they call "thermonuclear hypocrisy" and used satire targeted at pro-Brexit politicians. Led By Donkeys' main campaign consists of billboards containing past tweets by pro-Brexit politicians, or quotes presented as tweets. These tweets state the politicians' previous political positions, which according to the group have not stood the test of time.

"Lions led by donkeys" is a phrase used to imply a capable group of individuals are incompetently led. Coined in classical antiquity, the phrase was commonly used after World War I to describe senior commanders of militaries which participated in the war, most prominently those of the British Armed Forces. The historiography of the United Kingdom during the 20th century frequently described the infantry of the British Army as brave soldiers (lions) being sent to their deaths by incompetent and indifferent commanders (donkeys).
