The 1970 United States Senate election in Virginia was held on November 3, 1970. Incumbent Senator Harry F. Byrd Jr. was re-elected to his first full term after winning a race 4 years earlier to finish the remainder of his father's term.
Having switched from Democratic to an Independent shortly before the election, Byrd became the first non-Democrat to represent the state in the Senate since 1889. Byrd dominated the whole state except for the historic "antiorganization" strongholds in unionized coal counties of Southwest Virginia and a few heavily black counties of the Tidewater.
