Kir was not the only priest to sit in the Assemblée nationale in modern times. Abbé Pierre (1912-2007) also sat in the parliament from 1945 to 1951. He was a champion for the homeless and founded Emmaüs, the charity that helps those in poverty and homelessness.

The alcoholic cocktail named in honour of Félix Kir is the Kir. When he was Mayor of Dijon, he used to serve a blanc-cassis (white wine and blackcurrant flavoured liqueur, crème-de-cassis) to his guests. He made such a good job of popularising the drink that authorities decided to name it after him.
