Les Îles-de-la-Madeleine Regional County Municipality
Les Îles-de-la-Madeleine Regional County Municipality was a former regional county municipality and census division in the Gaspésie–Îles-de-la-Madeleine region of Quebec, Canada.
It was formed in 1981, and dissolved when all of its component municipalities amalgamated into the new Municipality of Les Îles-de-la-Madeleine on January 1, 2002, as part of the early 2000s municipal reorganization in Quebec.
Based on the last census prior to its dissolution, Les Îles-de-la-Madeleine consisted of:
| Name | Type/status | Land area in km2 | 2001 population | 1996 population |
| Cap-aux-Meules | Village | 3.60 | 1659 | 1661 |
| Fatima | Municipality | 26.00 | 2686 | 2966 |

| Totals | | 205.53 | 12,824 | 13,802 |
Following a 2004 referendum, the municipality of Grosse-Île separated from Les Îles-de-la-Madeleine and was reestablished on January 1, 2006. It is no longer incorporated within any regional county municipality, but remains part of the urban agglomeration of Les Îles-de-la-Madeleine.
