Woodlawn Cemetery is the name of a cemetery in Elmira, New York, United States. Its most famous burials are Mark Twain and his wife Olivia Langdon Clemens. Many members of the United States Congress, including Jacob Sloat Fassett are also interred there.

Within Woodlawn Cemetery is the distinct Woodlawn National Cemetery, begun with the interment of Confederate prisoners from the nearby Elmira Prison (dubbed "Hellmira" by its inmates) during the American Civil War. It is run by the United States Department of Veterans Affairs.

Both cemeteries are still active and together were added to the National Register of Historic Places in 2004.
