Qualeup is a town and locality of the Shire of Kojonup in the Great Southern region of Western Australia.

Lake Qualeup, after which the place is named, is located to the west of the townsite and locality, in neighbouring Kulikup.

[2][3] Qualeup and the Shire of Kojonup are located on the traditional land of the Kaniyang people of the Noongar nation.

[4][5][6] Qualeup was once a siding on the Donnybrook-Katanning railway and opened in 1912.

[7][8] Prior to this, in 1910, land was set aside at Qualeup for a potential townsite, but it took until 1921 for enough interest to materialise and Qualeup was gazeeted as a townsite in October 1924.
