The Brent crater is a meteor crater located north of Cedar Lake in Algonquin Provincial Park in the Nipissing District of Ontario, Canada. It is 3.8 km in diameter and the age is estimated to be 396 ± 20 million years (Middle Devonian). The crater is not exposed to the surface.
The crater was first discovered from aerial photographs in 1951. There is an observation tower on the rim of the crater and a hiking trail. There are two small lakes, Gilmour and Tecumseh, located in the crater. Unlike most Algonquin Park lakes, which are usually acidic, the water in these lakes contains bicarbonate; this is thought to be a result of some sedimentary deposits of limestone escaping removal by glaciers in the lower parts of the crater.
The crater was named after the nearby village of Brent.
