The third election to the City and County of Swansea Council was held in May 2004. It was preceded by the 1999 election and followed by the 2008 election.
All council seats were up for election. These were the third elections held following local government reorganisation and the abolition of West Glamorgan County Council. The Labour Party lost their majority on the authority.
The contests were fought by most of the main parties but Labour was the only one to contest the majority of seats.
