Portland, Oregon is divided into six sections: North Portland, Northeast Portland, Northwest Portland, South Portland, Southeast Portland, and Southwest Portland. There are 95 officially recognized neighborhoods, each of which is represented by a volunteer-based neighborhood association. No neighborhood associations overlap the Willamette River, but a few overlap the addressing sextants. For example, most addresses in the South Portland Neighborhood Association are South, but a portion of the neighborhood is west of SW View Point Terrace where addresses have a SW prefix. Similarly the Buckman Neighborhood Association spans both NE and SE Portland. Neighborhood associations serve as the liaison between residents and the city government, as coordinated by the city's Office of Community & Civic Life, which was created in 1974 and known as the Office of Neighborhood Involvement until July 2018. The city subsequently provides funding to this "network of neighborhoods" through district coalitions, which are groupings of neighborhood associations. A few areas of Portland are "unclaimed" by any of the 95 neighborhood associations in Portland.

Neighborhoods

Each neighborhood association defines its own boundaries, which may include areas outside of Portland city limits and (if mutually agreed) areas that overlap with other neighborhoods. Neighborhoods may span boundaries between the six sections (North Portland, Northeast Portland, Northwest Portland, South Portland, Southeast Portland, and Southwest Portland) of the city as well. The segmentation adopted here is based on Office of Community & Civic Life's district coalition model, under which each neighborhood is part of at most one coalition (though some neighborhoods are not included in any).
