The Margaret Chase Smith Library is an archive, museum, educational facility, and public policy center devoted to preserving the legacy of Margaret Chase Smith, promoting research into American political history, advancing the ideals of public service, and exploring issues of civic engagement. The library houses the political papers, documents, honors, photographs, and memorabilia stemming from the thirty-two year congressional career of former United States Senator Margaret Chase Smith.

The library is located on fifteen picturesque acres overlooking the banks of the Kennebec River in Senator Smith's hometown of Skowhegan, Maine. Dedicated in August of 1982, the facility opened to researchers the following year. It stands as a worthy tribute to Margaret Chase Smith's personal integrity, commitment to public service, and historical legacy.
