The Wayside Inn is a historic inn in Sudbury, Massachusetts, included on the National Register of Historic Places as part of the listed Wayside Inn Historic District. It became an inn called Howe's Tavern in 1716, making it one of the oldest continuously operating inns in the United States. The Beekman Arms Inn and others make various claims towards being "continuously operating", resulting from The Wayside Inn's closure period of 1861–1897 after the death of Lyman Howe.
