Spencer Butte is a prominent landmark in Lane County, Oregon, United States, described in the National Geodetic Survey as "a prominent timbered butte with a bare rocky summit" on the southern edge of Eugene, with an elevation of 2,058 feet (627 m).[1] Spencer Butte is accessible from Spencer Butte Park and has several hiking trails to the summit.[2] The tree cover on the butte is predominantly Douglas fir; however, the butte is treeless at its summit. The butte is the tallest point visible when looking south from downtown Eugene.
