Fort Bliss Main Post Historic District, Military historic district in El Paso, United States.

Fort Bliss Main Post Historic District is a military installation with preserved buildings from the late 1800s and early 1900s located in El Paso. The structures display Queen Anne and Colonial Revival styles typical of that era.

The Fort Bliss Main Post Historic District was listed on the National Register of Historic Places in 1998. Its earliest surviving buildings date from the post's initial construction between 1891 and 1899, when 27 buildings were erected; 16 of these are notable for their architecture. The district contains 343 contributing buildings, two contributing structures, and one contributing site.

The name honours William Wallace Bliss, the general who gave Fort Bliss its name; the post itself dates from 1848, though the Main Post buildings were raised in 1891–1899. Sixteen of the 27 surviving early buildings are noted for their architecture, so look for the two-storey hospital, Building 8, among the Queen Anne and Colonial Revival rows.

Access to the site is available during specific times and requires security clearance procedures. Guided tours led by military staff provide detailed information about the historic structures and their purposes.

A preserved two-story hospital building stands as a reminder of medical care during the military era. This structure offers insight into how health services were organized to support soldiers and their families.
