Shoemaker (formerly known as Teague Ring) is an impact structure (or astrobleme), the deeply eroded remnant of a former impact crater, situated in arid central Western Australia, about 100 km (62 mi) north-northeast of Wiluna. It is named in honour of planetary geologist Eugene Shoemaker. The prominent ring-like topographic feature, easily seen in satellite images, lies on the boundary between the Palaeoproterozoic Earaheedy Basin and the Archaean Yilgarn Craton. The area contains a number of seasonal salt lakes, the largest being Lake Teague.
