Jean Adrien François Lecanuet (4 March 1920 – 22 February 1993) was a French centrist politician.
Lecanuet was born to a family of modest means in Rouen and gravitated towards philosophy studies.
In August 1944, he was arrested along with a commando that had just blown up the Lille-Brussels railroad, but he managed to escape with the help of a Pole who had been drafted into the German army.
During the French legislative elections of 1973, Lecanuet negotiated the withdrawal of candidates with Pierre Messmer to ensure the success of the majority.
In 1986 at the beginning of the first period of "cohabitation" in modern French politics (a President and Prime Minister from opposing parties sharing power) Chirac nominated Lecanuet as Foreign Minister, but President François Mitterrand vetoed the appointment, along with some of Chirac's other nominees.
