HMS Mosquito was a Royal Navy coastal forces base at Alexandria, Egypt during the Second World War.

The base and slipways were situated alongside King Farouk's palace.

The accounts were centralised at HMS Nile and Mosquito was established as an independent command.

The base was in operation until being paid off to Care and Maintenance on 1 December 1945.

The site was extended to include a number of establishments around the south-eastern corner of the Mediterranean.
