The '''U.S. National Science Foundation''' ('''NSF''') is an [[Independent agencies of the United States government#Examples of independent agencies|independent agency]] of the [[Federal government of the United States|United States federal government]] that supports fundamental [[research]] and [[education]] in all the non-medical fields of [[science]] and [[engineering]]. Its medical counterpart is the [[National Institutes of Health]]. With an annual budget of about $9.9 billion (fiscal year 2023), the NSF funds approximately 25% of all federally supported [[basic research]] conducted by the [[List of American institutions of higher education|United States' colleges and universities]].<ref name="NSF Site"/><ref>{{Cite web |title=Budget, Performance and Financial Reporting – About NSF {{!}} NSF – National Science Foundation |url=https://new.nsf.gov/about/budget |access-date=2024-03-14 |website=new.nsf.gov |language=en}}</ref> In some fields, such as [[mathematics]], [[computer science]], [[economics]], and the [[social sciences]], the NSF is the major source of federal backing.

NSF's director and deputy director are appointed by the [[president of the United States]] and [[Advice and consent|confirmed]] by the [[United States Senate]], whereas the 24 president-appointed members of the [[National Science Board]] (NSB)<ref name="nsf">{{cite web|url=https://www.nsf.gov/nsb/|title=National Science Board|website=National Science Board}}</ref> do not require U.S. Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while the NSB meets six times a year to establish its overall policies.
