The 30 Commando Information Exploitation Group is a Royal Marines unit of the British Armed Forces. The unit resources include communications, information operations, information systems, intelligence, surveillance, and Target Acquisition and Reconnaissance (ISTAR).

The unit's title harks back to the original 30 Commando (which in turn became 30 Assault Unit RM), formed in 1942. This unit was tasked to move ahead of advancing Allied forces, or to undertake covert infiltrations into enemy territory by land, sea or air, to capture much needed intelligence, in the form of codes, documents, equipment or enemy personnel.

In 2010 the unit, which had formerly been known as the HQ & Signals Squadron Royal Marines and then as the UK Landing Force Command Support Group, was renamed 30 Commando Information Exploitation Group.

In 2013, 30 Commando Information Exploitation Group were granted the freedom of Littlehampton, West Sussex, in honour of the original unit being based in the town during the Second World War.
