Location of Gyeongju

The legislative branch consists of the Gyeongju City Council, with 21 members as of 2009. The present City Council was formed from the merger of the old Gyeongju City Council with the Wolseong County Council in 1991. Most subdivisions of Gyeongju elect a single member to represent them in the Council, but Angang-eup is represented by two members because of its large population, and two of the representatives serve combined districts composed of two dong. Like the mayor, the council members were last elected in 2006, except for a small number elected in more recent by-elections.

The central administration is composed of a City Council committee, five departments, two subsidiary organs, a chamber (the auditor), and six business offices. The five departments are the departments of Planning and Culture, Autonomous Administration, Industry and Environment, Construction and Public Works, and the National Enterprise Committee; these oversee a total of 29
