Trent is a rural locality of the Shire of Denmark in the Great Southern region of Western Australia. The Frankland River forms much of the western border of Trent. Most of the locality is covered by national park, with the Mount Frankland South National Park in the south and south-west, the Mount Frankland National Park in the north-west, and the Mount Roe National Park in the east.

Trent and the Shire of Denmark, according to the shire's website, are located on the traditional land of the Bibulman and Mineng people of the Noongar nation. The Mineng's traditional lands cover the majority of the shire while the Bibulman's traditional lands are to the west and, according to other sources, do not extend into the Shire of Denmark.
