Happy Valley is a locality in the Local Government Area of the Golden Plains Shire.

[2] Gold was discovered in the area, originally called "Wardy Yallock" (thought to have meant "winding yellow river" of Aboriginal origins) in 1849 as part of the Australian gold rushes, with intensive mining beginning in 1853.

[3] The Aboriginal name is also given as Molong ghip.

The naming comes from the amount of gold found in the area.
