David Harold Bieter (born November 1, 1959) is an American politician and attorney who served as mayor of Boise from 2004 to 2020.

He later served as a land-use specialist in the Ada County Prosecutor's Office in Boise before establishing a private practice, specializing in municipal law.

[5] In 2004, Bieter was elected Boise mayor in an open-seat, nonpartisan contest, defeating Republican Party activist Chuck Winder and Ada County Sheriff Vaughn Killeen.

As mayor, Bieter has emphasized the need to protect and enhance Boise's livability to create "a welcoming city and a center for business, culture, education and outdoor recreation."

He is credited with helping to expand Boise's parks system, championing the opening of four new neighborhood libraries, and promoting a "housing first" approach to combating homelessness.

[5] Under Bieter, Boise has expanded the purchase of open space and easements in the foothills areas north of the city to protect wildlife habitat, water quality, and recreation opportunities.

[10] In 2015, Bieter was instrumental in creation of Trailhead, a non-profit business incubator supported by the City of Boise, its redevelopment agency, and local entrepreneurs.

He also worked with the Boise School District to launch Idaho's first public preschool program; after just two years, a study showed a sizable increase in reading scores.
