The Letterman Army Hospital — established around 1898 and redesignated as the Letterman Army Medical Center (LAMC) in 1969 — was a U.S. Army facility located on the Presidio of San Francisco in San Francisco, California, USA. It was abandoned in 1994. Some of the original 1898 buildings still exist and now house the Thoreau Center for Sustainability. The Letterman Army Medical Center built in the 1960s era was completely demolished to make way for Lucas Digital Arts.
The hospital, built in 1898 and named in 1911 for Major Jonathan Letterman, MD (1824–1872), was featured in every US foreign conflict in the 20th century and remained in service until the army base was decommissioned in 1995.
The building was abandoned in 1994 when the base was transferred to the National Park Service and was demolished in 2002. In 2005, Lucasfilm opened the Letterman Digital Arts Center on the site of the old hospital.
