The 2014 United States Senate election in Delaware was held on November 4, 2014, to elect a member of the United States Senate to represent the State of Delaware, concurrently with other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections. This election was the fifth consecutive even-number year in which a senate election was held in Delaware after elections in 2006, 2008, 2010, and 2012. Incumbent Democratic Senator Chris Coons ran for re-election to a first full term in office. He was unopposed for the Democratic nomination and defeated Republican businessman Kevin Wade in the general election.
Democratic senator Joe Biden was re-elected to a seventh term in 2008, defeating Republican political commentator Christine O'Donnell by 65% to 35%. At the same time, he was elected Vice President of the United States and resigned his Senate seat to be sworn in as vice president in January 2009. Delaware Governor Ruth Ann Minner appointed Biden's longtime aide Ted Kaufman to the seat until a special election was held in November 2010. In the election, Christine O'Donnell ran again and upset U.S. Representative and former governor Mike Castle in the Republican primary to face Democrat Chris Coons, who had run unopposed for his party's nomination. In the general election, Coons defeated O'Donnell by 57% to 40% and was sworn in later that month.
