Yalgoo is a town in the Murchison region, 499 kilometres (310 mi) north-north-east of Perth and 118 kilometres (73 mi) east-north-east of Mullewa.
Yalgoo has a semi-arid climate with hot summers and mild to cool winters.
The Court House, which was moved from Day Dawn near Cue in 1921, is now a museum with displays of old photographs, lots of gold rush history, the usual displays of old domestic items and some interesting Aboriginal artifacts from the local area. Next to the Courthouse, the community has restored the old Yalgoo police station and jail. The old jail and police station were built in the town in 1896 and although the cells are very small they were a vast improvement on the stick and chain method previously used for incarceration.
