Fort Rosecrans National Cemetery is a federal military cemetery in the city of San Diego, California. It is located on the grounds of the former Army coastal artillery station Fort Rosecrans and is administered by the United States Department of Veterans Affairs. The cemetery is located approximately 10 miles (16 km) west of Downtown San Diego, overlooking San Diego Bay and the city from one side, and the Pacific Ocean on the other. Fort Rosecrans is named after William Starke Rosecrans, a Union general in the American Civil War. The cemetery was registered as California Historical Landmark #55 on December 6, 1932. The cemetery is spread out over 77.5 acres (31.4 ha) located on both sides of Catalina Blvd.

Many Fort Rosecrans interments date to the early years of the California Republic, including the remains of the casualties of the Battle of San Pasqual, in which 19 of Brigadier Stephen W. Kearny's men and an untold number of Californios lost their lives. Initially, the dead were buried where they fell, but by 1874 the remains had been removed to the San Diego Military Reservation. Eight years later, the bodies were again reinterred at what is now Fort Rosecrans National Cemetery. In 1922, the San Diego chapter of the Native Sons and Daughters of the Golden West had a large boulder brought from the battlefield and placed at the gravesite with a plaque affixed that lists the names of the dead.
