one of a Native American people living near the Ottawa River in Canada, 1620s, from French Algonquin, perhaps a contraction of Algoumequin, from Micmac algoomeaking "at the place of spearing fish and eels." But Bright suggests Maliseet (Algonquian) elægomogwik "they are our relatives or allies."

Algonquian was the name taken late 19c. by ethnologists to describe a large group of North American Indian peoples, including this tribe. The Algonquin Hotel (59 W. 44th Street, Manhattan) opened 1902 and was named by manager Frank Case for the tribes that had lived in that area. A circle of journalists, authors, critics, and wits began meeting there daily in 1919 and continued through the twenties; they called themselves "The Vicious Circle," but to others they became "The Round Table."
