Emigrant Pass is a gap in the Cascade Range in the U.S. state of Oregon. It is about 0.5 miles (0.8 km) west of on the border between Klamath and Lane counties. Originally called Willamette Pass, it lay along a primitive road that paralleled the Middle Fork Willamette River to near the crest. The gap's name was changed in 1960, when the mountain pass used by Oregon Route 58 north of Odell Lake was named Willamette Pass.
