Salubria Lodge No. 31 is a historic Masonic building located at 85 W. Central Street in Cambridge, Washington County, Idaho, United States. Built in 1922 to replace an earlier meeting hall destroyed by fire, it is a two-story building made of red brick and concrete with a sloped roof over an attic space designed by Watkins & Thompson. Above the entrance are two stained glass windows depicting the emblem of the Masonic order. A metal roof covering has been added to protect the original wooden roof from heavy snowfall.
