Auglaize County /ˈɔːɡleɪz/ is a county located in the U.S. state of Ohio. As of the 2010 census, the population was 45,949. Its county seat is Wapakoneta.

The county is named for the Auglaize River. Some sources say it is a corruption of the French description of the clay (glaise) water (eau), whereas others say it comes from a Native American word meaning 'fallen timbers'. Another weak possibility according to Lakehistory.info is that it could have been the French term la glace [*aux glaces?], which means 'mirror', or 'ice' ['at the ices'?].
