阿卡迪亚人（法语：Acadiens；英语：Acadians）是17世纪定居于阿卡迪亚的法国殖民者的后裔，其中许多是梅蒂人（早期法国殖民者与原住民的混血儿）。该殖民地位于现今加拿大东部的海洋省份（新斯科舍、新不伦瑞克和爱德华王子岛）、魁北克局部以及现今美国缅因州至肯尼贝克河部分。尽管现在绝大多数阿卡迪亚人和魁北克人是说法语的加拿大人，但阿卡迪亚是一个明显不同的新法兰西殖民地，它在地理上和行政上与加拿大的法国殖民地（今天的魁北克）分隔，其结果是阿卡迪亚人和魁北克人发展出了各自不同的历史和文化，他们也发展出了有些许差别的法语。法兰西学院肩负着维护法语官方语言地位的使命，自从阿卡迪亚人与学院的联系被分隔，他们使用的法语独立演化，也因此阿卡迪亚人所使用的法语保留了一些在法国已经遗失的17世纪法语元素。那些后代成为了阿卡迪亚人的法国移民来自法国的各个区域，但主要来自于城市。

The Acadians (French:Acadiens, IPA: [akadjɛ̃]) are the descendants of French colonists who settled in Acadia during the 17th and 18th centuries, some of whom are also Métis. The colony was located in what is now Eastern Canada's Maritime provinces (Nova Scotia, New Brunswick, and Prince Edward Island), as well as part of Quebec, and present-day Maine to the Kennebec River. Although today most of the Acadians and Québécois are French-speaking (francophone) Canadians, Acadia was a distinctly separate colony of New France. It was geographically and administratively separate from the French colony of Canada (modern-day Quebec). As a result, the Acadians and Québécois developed two distinct histories and cultures. They also developed a slightly different French language. France has one official language and to accomplish this they have an administration in charge of the language. Since the Acadians were separated from this council, their French language evolved independently, and Acadians retain several elements of 17th-century French that have been lost in France. The settlers whose descendants became Acadians came from many areas in France, but especially regions such as Île-de-France, Normandy, Brittany, Poitou and Aquitaine.
