Boise is a neighborhood in the North and Northeast sections of Portland, Oregon. It is approximately bounded by Interstate 5 on the west, N Skidmore St. on the north, NE Rodney Ave. on the east, and N Kerby St. and NE Fremont St. on the south. The southern portion of N Mississippi Ave. forms the commercial core of the area. The neighborhood was named in honor of Reuben P. Boise, a Portland School Board member during the 1850s.

In the mid-20th century, Boise residents included a high percentage of African Americans, relative to other Portland neighborhoods. This changed rapidly in the 2000s. The 2000 Census recorded 48% of the population identifying as Black or African American, either alone or mixed with another race. By the time of the 2010 Census, this number had fallen to 26.6%, largely supplanted by Whites. This demographic change has accompanied rapid development and gentrification in the neighborhood.
