Portland street names have gone through a number of changes through the years. Many of those came about by the annexation of surrounding towns into the City of Portland. This usually brought about a new slew of duplicate street names.

An ongoing project of mine has been to document the name changes. These lists are incomplete, and if you know of any additions or corrections, I would be most happy to include them. Email me.

There were two major changes to Portland Street names and numberings. The first occurred in 1891, when a number of surrounding cities were annexed to Portland. The City Council passed Ordinance #7446 which provided for the numbering of streets. These included East Portland, Albina, Sellwood.

The second major change occurred in 1931, when the City Council passed Ordinance #61325 changing the number of house numbers blocks from 20 to per block. Also, all addresses were standardized into N, NE, NW, SE, and SW.
