John Simonds (26 June 1883 – 29 May 1945) was a British trade union leader.
He tried unsuccessfully to bring about a merger with the Poor Law Officers' Union, while opposing unification with the National Association of Local Government Officers (NALGO).
In 1929, these were abolished, and members' employment was transferred to local authorities.
NALGO took the opportunity to try to recruit NPLOA branches individually.
Simonds strongly opposed this, but was spurred to negotiated a merger.
