Government of Portland, Oregon

The government of Portland, Oregon, is based on a mayor–council government system. Elected officials include the mayor, a 12-member city council, and a city auditor. The city council is responsible for legislative policy, while the mayor appoints a professional city manager who oversees the various bureaus and day-to-day operations of the city. The mayor is elected at-large, while the council is elected in four geographic districts using single transferable vote, with 3 winning candidates per district. Portland's current form of government was approved by voters in a 2022 ballot measure, with the first elections under the new system held in 2024.

Prior to 2022, Portland used a city commission government system, with the mayor and four city commissioners directly overseeing operations of the city bureaus. Under the previous system, all elected officials were elected at-large and served four-year terms with no term limits. Portland began using a commission form of government in 1913 following a public vote on May 3 of that year.
