Desjardins is a topographic surname meaning "of the gardens" — from the French des jardins, literally "of the (plural) gardens." The word jardin (garden) comes from the Old Frankish gard or gardo, an enclosed space or enclosure. A garden in medieval usage was any enclosed cultivated area — not merely an ornamental flower garden but a kitchen garden, an orchard, or a market garden that supplied food to a community. A family identified as "the people of the gardens" lived near, worked in, or owned such cultivated land.
The most significant institution bearing the Desjardins name is the Mouvement Desjardins — the cooperative financial group founded by Alphonse Desjardins (1854–1920) in Lévis, Quebec, in 1900. Alphonse Desjardins, inspired by the European cooperative movement, established the first caisse populaire (people's bank) in North America as a response to the usurious interest rates charged by private lenders to Quebec's working-class and farming population. His model spread across Quebec and eventually across Canada: today the Mouvement Desjardins is the largest cooperative financial group in Canada, with over 7 million members and assets exceeding $400 billion. The Desjardins name is synonymous with Quebec cooperative values — solidarity, mutual aid, and economic democracy.
The Desjardins families of Quebec trace primarily to emigrants from Normandy and western France in the seventeenth and eighteenth centuries. The name appears in Quebec parish records from the early colonial period onward, with particular concentration in the Quebec City region and the Beauce — the agricultural heartland south of Quebec City along the Chaudière River. The Beauce is sometimes called "le pays des Desjardins" in regional Quebec folklore, reflecting the name's density in that region.

His Mouvement Desjardins grew to become the largest cooperative financial institution in Canada, with over $400 billion in assets. He is one of the great social innovators of Canadian history.

Desjardins families emigrated from Quebec to New England as part of the large Franco-American migration of the nineteenth and early twentieth centuries. Like other Quebec surnames, Desjardins appears in the mill towns of Massachusetts, Rhode Island, Connecticut, and New Hampshire in the 1880–1920 period. The name is less common in New England than Tremblay or Gagnon but still represents a significant Franco-American presence.
In Belgium, Desjardins is also a native surname — Belgian families of the same name have a completely independent origin from the French-Canadian Desjardins, though they share the same topographic etymology. The Belgian Desjardins are primarily from Wallonia (French-speaking Belgium) and trace their name to the same horticultural tradition.
Desjardins research in Quebec follows the standard Quebec genealogical path through the PRDH database (prdh-igd.com) and the BAnQ civil records. The Beauce region south of Quebec City — the Chaudière River valley — is the primary ancestral area for many Quebec Desjardins families. The parish records of Saint-Joseph-de-Beauce and Sainte-Marie-de-Beauce are particularly relevant.
For Franco-American Desjardins families in New England, the Société Historique Franco-Américaine and US census records from 1880–1940 document the migration pattern. Quebec emigrant communities in Manchester NH, Lowell MA, and Lewiston ME all contain Desjardins households. The key is to trace from the New England address back to the Quebec parish of origin, then into the PRDH database.
