Oregon Route 99W is a state-numbered route in Oregon, United States that runs from OR 99 and OR 99E in Junction City north to I-5 in southwestern Portland. Some signage continues it north to US 26 near downtown, but most signage agrees with the Oregon Department of Transportation's (ODOT) description, ending it at I-5. OR 99W is known by ODOT as the Pacific Highway West No. 1W (see Oregon highways and routes); that highway continues north through downtown (along a former extension of OR 99W) to the Pacific Highway No. 1 (I-5) in northern Portland, as well as south on OR 99 to the Pacific Highway (I-5) in Eugene.

Until around 1972, OR 99W was U.S. Route 99W, rejoining OR 99E (former US 99E) in northern Portland. US 99 then continued north along present I-5 into Washington; the next segment still numbered 99 is WA 99 south of Seattle.
