# 1944 United States Senate elections

The 1944 United States Senate elections coincided with the re-election of Franklin D. Roosevelt to his fourth term as president. The 32 seats of Class 3 were contested in regular elections, and three special elections were held to fill vacancies.
The Democrats retained their large majority, although they lost a net of one seat to the Republicans. Republicans won open seats in Indiana, New Jersey, and Missouri, and defeated an incumbent in Iowa. However, Democrats defeated incumbents in Connecticut, Pennsylvania, and North Dakota. The Democratic majority was further reduced to 56-39-1 throughout mid-term appointments.
