Oregon Route 43 is an Oregon state highway that runs between the cities of Oregon City and Portland, mostly along the western flank of the Willamette River. While it is technically known by the Oregon Department of Transportation as the Oswego Highway No. 3 (see Oregon highways and routes), on maps it is referred to by its route number or by the various street names it has been given.
