Everett Alvarez Jr. (born December 23, 1937) is a retired United States Navy officer who endured one of the longest periods as a prisoner of war (POW) in U.S. military history.

Alvarez was the first U.S. pilot to be shot down and detained during the Vietnam War and spent over eight years in captivity, making him the second longest-held U.S. POW, after U.S. Army Colonel Floyd James Thompson.

Alvarez endured eight years and seven months of brutal captivity by the North Vietnamese at the Hỏa Lò Prison (sarcastically known as the "Hanoi Hilton" by fellow POWs), in which he was repeatedly beaten and tortured.

His final assignment was in Program Management at the Naval Air Systems Command in Washington, D.C., from October 1976 until his retirement from the Navy on June 30, 1980.

In January 2025, Secretary of the Navy Carlos Del Toro announced that the seventh Constellation-class frigate would be named USS Everett Alvarez in his honor.
