Clark Veterans Cemetery is located in Clark Freeport Zone, Angeles City, Philippines. The cemetery is the burial place for thousands of mainly American veterans and Filipino Scouts who served in the United States Army, and who died in conflicts other than World War II or on military bases in the Philippines.

The origins of the Clark Veterans Cemetery can be traced to 1900 after the conclusion of the Spanish–American War. As a result of the war, the United States acquired the Philippines from Spain and established a number of US Army posts throughout the islands. These included a large Army base in Manila named Fort William McKinley and an even larger US Cavalry base 50 miles north of Manila called Fort Stotsenburg (now Clark). Similarly the US Navy, after Rear Admiral George Dewey defeated the Spanish Navy in the Battle of Manila Bay, created naval bases including one at Sangley Point in Cavite. Many of these military installations had post cemeteries. The largest was the cemetery at Fort William McKinley in Manila. During World War II, the Fort McKinley military post cemetery was the scene of heavy fighting because it was strategically situated on a hill that overlooked the city and Manila Bay. During the battle to liberate Manila in early 1945, thousands of graves and cemetery records were lost or damaged, including a large marble obelisk Monument to the Unknown Dead.

After World War II, in 1946, the US and Philippine governments determined that this site would be the best location for a new cemetery and memorial to honor those who died throughout Southeast Asia during World War II. However, in order to accommodate as many as 17,000 World War II remains, the US Government had to find a new home for the thousands of non-World War II dead already buried there. That new home was to be at Fort Stotsenburg (now Clark). From January to May 1948, all the non-World War II dead at the Fort McKinley cemetery were disinterred and relocated to the newly created military post cemetery at Fort Stotsenburg, which became known as the Clark Veterans Cemetery. Three other older US military post cemeteries were also moved and relocated to this new consolidated non World War II military post cemetery at Fort Stotsenburg. These three cemeteries were the US Navy Sangley Point Military Cemetery and two smaller and older military cemeteries that had previously existed at Fort Stotsenburg called Stotsenburg I and II. Later, in 1949, Fort Stotsenburg itself was transferred from the U.S. Army to the United States Air Force and renamed Clark Air Force Base. This is the site of the Clark Veterans Cemetery.

The Clark Veterans Cemetery is located just inside the main gate of the former base and consists of 20.365 acres (8.241 ha) with room for 12,000 plots. Work began on preparation of the new site in 1947 with the first batch of graves used for burial of remains arriving from Fort McKinley in January 1948. By December 1950 all of the non-World War II dead from Fort McKinley, Sangley Point and Stotsenburg I and II were consolidated in the new Clark Veterans Cemetery, with 5,056 remains having been relocated. This then enabled construction of the new Manila American Cemetery and Memorial in Taguig for the burial of the World War II dead.

The 1991 Mount Pinatubo volcanic eruption spewed volcanic ash for miles and covered everything with 8 inches (200 mm) to 15 inches (380 mm) of ash. Later a soft weedy and spongy surface where vegetation grew on top of the ash and an undulating ground surface created when the ash was removed from the flat horizontal stones which now often becomes covered with debris can also be seen. The ash damage is most evident with the lower half of all vertical epitaphs totally hidden from view.

In 1994, veterans from Veterans of Foreign Wars (VFW) Post 2485 stepped forward to help halt the decay. After 3 years of neglect, members of the Post volunteered to remove overgrown vegetation and removing ash. Since then, VFW Post 2485 members have administered and maintained the cemetery in a ‘state of arrested decay’.

A not for profit organization, the Clark Veterans Restoration Association, was created to promote the cemetery's history, to educate the public and advocate for the US Government to reassume its responsibility to administer the cemetery.

In 2011, an American small business, Peregrine Development International, operating at Clark in conjunction with the Kuwaiti sponsored Global Gateway Logistics City Project, collaborated with the VFW Post 2485 to donate and construct a new perimeter fence and gate.
