Minor tombs in the Valley of the Kings are larger, multiple chambered tombs. These minor tombs served various purposes, some were intended for burials of lesser royalty or for private burials, some contained animal burials and others apparently never received a primary burial.

While some of these tombs have been open since antiquity, the majority were discovered in the 19th and early 20th centuries during the height of exploration in the valley. Tombs in the Valley of the Kings are assigned a numerical "KV" (for Kings' Valley)
