Upper Warren is a rural locality of the Shire of Manjimup in the South West region of Western Australia.

The Warren River runs from through the locality from east to west while, in places, also forming its border.

[2][3] Upper Warren is located on the traditional land of the Bibulman people of the Noongar nation.

The St Mark's Anglican Church and the Rockbridge hut are also in Upper Warren and are on the Western Australian State Register of Heritage Places.

[9] The Clover Cottage was built by the Wheatleys in 1875,[10] Riverdale House by the Mottrams in 1895, just like Rockbridge,[11] and Young's Homestead by the Clarkes in 1880.
