The 2015 Connecticut State Senate 23rd district special election was held on February 24, 2015, in order to fill Andres Ayala Jr.'s seat after he was appointed to be the director of the Connecticut Department of Motor Vehicles. Former Senator Ed Gomes, the nominee of the Connecticut Working Families Party, won the special election and regained the seat that he had held before Ayala Jr. had defeated him in the 2012 primary.
Gomes was the first person elected to a state legislature with only the nomination of the Working Families Party. He was also the first third-party candidate elected to the Connecticut state legislature since the Socialist Party of America elected four of its members to the state legislature in 1938.
