The Institution of Professionals, Managers and Specialists (IPMS) was a trade union representing managers and other people with professional qualifications in the United Kingdom, with a majority of members working in the civil service.

The spur for its formation was the creation of the Whitley Council system, on which the new union qualified for two seats.

Following privatisation of the jobs of many of its members, IPCS changed its name to the Institution of Professionals, Managers and Specialists, in 1989.
