The MRWA P class was a class of steam locomotives operated by the Western Australian Government Railways (WAGR) and later the Midland Railway of Western Australia (MRWA) from 1896.

In July and August 1896, the WAGR took delivery of two steam locomotives from James Martin & Co, Gawler, South Australia.

They were basically a 4-4-0 version of the WAGR's 4-6-0 G class, and identical to the South Australian Railways Z class, save for a bogie tender in place of the SAR six wheel tender.

[2] Both were sold in 1912 to the MRWA, however they were underpowered and after the delivery of its five new C class locomotives, were relegated to shunting duties at Midland Junction.
