Clansman is the name of a combat net radio system (CNR) used by the British Army from 1976 to 2010 which was developed by the Signals Research and Development Establishment (SRDE) in the 1960s, to satisfy a General Staff Requirement (GSR) from 1965. Built by Racal, Mullard Equipment Ltd (MEL) and Plessey, Clansman represented a considerable advance over existing radios being offered to the Armed Forces at the time.

It replaced the ageing Larkspur radio system, being, reliable and very much lighter. The technological advances achieved in the design of Clansman allowed the introduction of Single SideBand (SSB) operation and NarrowBand Frequency Modulation (NBFM) to forward area combat net radio for the first time.

Clansman was in use by British forces from the late 1970s and saw service in most recent UK military operations. It was replaced in the mid-2000s by the new Bowman communication system
