The 1934 United States Senate election in Vermont took place on November 6, 1934. Incumbent Republican Warren Austin successfully ran for re-election to a full term in the United States Senate, defeating Democratic candidate Fred C. Martin. Austin was elected in a 1931 special election to replace Frank C. Partridge, who was appointed to fill the vacancy created by the death of Frank L. Greene. To date, Martin's 48.37% vote share remains the largest a Democrat has ever received for Vermont's Class I Senate seat.
Senator Austin undertook an extensive advertising and letter-writing campaign but did not directly address his opponent, who was not considered a strong threat.
