阿尔吉克语系（英：Algic languages）是北美洲原住民语言语系，主要使用在北美洲的北部地区，包括加拿大和美国的一些省份。语系内多数语言属于阿尔冈昆语族，分布在北美东岸至落基山脉的地区，此外还有尤罗克语和维约特语，分布在加州西北。

原始阿尔吉克语已通过比较原始阿尔冈昆语和尤罗克语、维约特语而构建出来。原始语使用范围据估计在太平洋西北地区哥伦比亚河沿岸。

阿尔吉克语系的概念最早由美国语言学家爱德华·萨丕尔，在发现上述两门加州语言与阿尔冈昆语言之间的联系后提出。

The Algic (also Algonquian–Wiyot–Yurok or Algonquian–Ritwan) languages are an indigenous language family of North America. Most Algic languages belong to the Algonquian family, dispersed over a broad area from the Rocky Mountains to Atlantic Canada. The other Algic languages are the Yurok and Wiyot of northwestern California, which despite their geographic proximity are not closely related. All these languages descend from Proto-Algic, a second-order proto-language estimated to have been spoken about 7,000 years ago and reconstructed using reconstructed Proto-Algonquian and the attested languages Wiyot and Yurok.
