Groupe Caisse d'épargne was a group of French savings banks that were converted into cooperative banks by legislation enacted in 1999.: 175 Its roots went back to the founding in 1818 of the Caisse d'Épargne et de Prévoyance de Paris, initiated by Benjamin Delessert and the Duke of La Rochefoucauld-Liancourt.
The group was active in retail and private banking, with around 4700 branches in the country, as well as holding a significant stake in the publicly traded investment bank Natixis. In 2009, it merged with Groupe Banque Populaire to form Groupe BPCE. A retail banking network under BPCE still uses the Caisse d'Épargne brand name.
