The James Tanner Amphitheater is a historic wood and brick amphitheater located at Arlington National Cemetery in Arlington County, Virginia, in the United States. The amphitheater, which was originally unnamed, was constructed in 1873 and served as the cemetery's main public meeting space until the completion of Memorial Amphitheater in 1920. The amphitheater was informally called the Old Amphitheater from 1920 to May 2014, when it was renamed the James R. Tanner Amphitheater in honor of James R. Tanner, a disabled American Civil War veteran and influential veterans' organization leader.
