The National Society of Professional Surveyors (NSPS) is the United States of America FIG Member Association representing the surveying profession in the United States, having a membership of over 17,000. 

 NSPS strives to establish and further common interests, objectives, and political effort that would help bind the surveying profession into a unified body in the United States.

 Established 35 years ago in 1983 and incorporated in 1991 NSPS merged with the American Congress on Surveying and Mapping (ACSM) in 2012, an FIG member association since 1959. In 2016 ACSM celebrated the 75th anniversary of its founding.
