HMAS Melville is a former Royal Australian Navy (RAN) shore base located in Darwin, Northern Territory, in Australia.

A high-powered Wireless Transmitting Station was built in 1939 and also the construction of fuelling facilities, boom depot and improvements to Darwin's water supply.

The depot was renamed HMAS Penguin IV with the outbreak of World War II.

The base was subjected to numerous bombing raids during the Battle of Darwin and suffered significant damage.
