Yalup Brook is a former small town located in the South West of Western Australia along the South Western Highway, between Waroona and Harvey.

The railway line opened in 1893 and a station was established in the late 1890s.

[1][2] Little development occurred as the town is situated so close to Waroona and Wagerup.

The name of the town comes from a nearby brook of the same name, first recorded by a surveyor in 1889.

The name of Yorlup appears in earlier maps and was recorded as early as 1833.
