Wellington Mill is a locality in the Ferguson River valley, in the Greater Bunbury sub-region of South West region of Western Australia.

In 1881 a timber mill was established in the area.

In 1896 the Canning Jarrah Timber Company established a timber mill and town at Wellington Mill, which when established was the largest private timber town in Western Australia.

The timber mills closed in 1929 and a fire destroyed most of the town in 1950.

[3] It began in 1995 when gnomes were placed in the intersection in protest of the construction of a roundabout,[4] and has been added to by visitors over time.
