The Auglaize River (Shawnee: Kathinakithiipi) is a tributary of the Maumee River in northwestern Ohio in the United States. It drains a primarily rural farming area in the watershed of Lake Erie. The name of the river was derived from the French term for it. The French called it "rivière à la Grande Glaize" (later spelled as "glaise", meaning river of Great Clay), referring to the soil in the area. The river rises in southeastern Allen County, approximately southeast of Lima and north of Indian Lake. It flows southwest to Wapakoneta, then generally north in a zigzag course, past Delphos, Fort Jennings and Oakwood. It joins the Maumee from the south at Defiance, approximately east of the mouth of the Tiffin River at . It receives the Ottawa River from the southeast in western Putnam County, northwest of Lima. It also receives the Blanchard River in western Putnam County. It receives the Little Auglaize River from the south in eastern Paulding County. It receives Flatrock Creek from the west in northeastern Paulding County. During the days of the Ohio Country in the 18th century, the area around the river was inhabited by the Ottawa. During the mid-1790s the area near the mouth of the Auglaize surpassed Kekionga to the west as the center of Indian influence. Fort Defiance was constructed in 1794 near the confluence of the Auglaize and the Maumee by General Mad Anthony Wayne. Fort Amanda, constructed along the river southwest of Lima in 1812, was an important American outpost during the War of 1812.
