Camp Hulen was a military training camp near Palacios, Texas, United States that operated from 1925 until 1946 and, at one time, supported the largest concentration of troops for field training in the United States military.
In 1940, the War Department leased Camp Hulen for anti-aircraft training of National Guard units from around the country.
German prisoners of war were housed at Camp Hulen from 1943 to 1945.
In 1946, the War Department returned Camp Hulen to the National Guard, which found it had become too small.
The army air base became the Palacios Municipal Airport in 1965.
