The Oregon Rail Heritage Foundation (ORHF) is a registered non-profit organization based in Portland, Oregon, United States. Composed of a partnership of several all-volunteer non-profit groups dedicated to maintaining regional vintage railroad equipment, the ORHF was initially formed "to secure a permanent home for the City of Portland's steam locomotives, preserve the Brooklyn Roundhouse, and establish a Rail and Industrial Heritage Museum.”

The Oregon Rail Heritage Center (ORHC) is a railway museum in Portland, Oregon. Along with other rolling stock, the museum houses three steam locomotives owned by the City of Portland: Southern Pacific 4449, Spokane, Portland & Seattle 700, and Oregon Railroad & Navigation Co. 197, the first two of which are restored and operable. The center opened to the public on September 22, 2012. The project to establish the center was led by the Oregon Rail Heritage Foundation (ORHF), a non-profit organization, which was renamed from the Oregon Heritage Steam Foundation in 2002. The non-profit Oregon Steam Heritage Foundation was formed in 2000. The museum site is in Southeast Portland.
