The National Republican Senatorial Committee (NRSC) is the Republican Hill committee for the United States Senate, working to elect Republicans to the Senate. The NRSC was founded in 1916 as the Republican Senatorial Campaign Committee. It was reorganized in 1948 and renamed the National Republican Senatorial Committee. It has been chaired by Senator Tim Scott from South Carolina since 2025.
The NRSC helps elect Republican incumbents and challengers primarily through fundraising.
