List of Oregon's Most Endangered Places

Oregon's Most Endangered Places is a list established in 2011, compiled by the American historic preservation non-profit Restore Oregon (formerly the Historic Preservation League of Oregon), that raises awareness of Oregon's "historic treasures in need of the advocacy and support to save them from demise".

Beginning in 2015, new sites were listed while some previously listed sites remained on the list. After 2020, Restore Oregon did not compile a yearly list. Many of the sites are also listed on the National Register of Historic Places (NRHP).
