The St. Lawrence Iroquoian people were an Indigenous group that lived in the St. Lawrence River Valley, primarily in what is now Canada and New York. They are known for their unique language, which is part of the Iroquoian language family, and for their agricultural practices, including the cultivation of crops like corn, beans, and squash. Historically, the St. Lawrence Iroquoians built fortified villages and engaged in trade with neighboring tribes. They are often associated with the St. Lawrence Iroquoian language, which is now extinct, and their culture contributed to the broader Iroquoian heritage, influencing groups such as the Haudenosaunee.
