KV64 is the tomb of an (as yet) unknown 18th Dynasty burial re-used in the 22nd Dynasty for an intrusive burial of the lady Nehmes Bastet, a singer at the temple of Karnak, in the Valley of the Kings, near Luxor, Egypt. It is located on the pathway to Tomb KV34 (Thuthmosis III) in the main Valley of the Kings. KV64 was found by Dr Elena Pauline-Grothe of the University of Basel.
"KV64" (with quotation marks) had previously been tentatively employed in reference to an anomaly detected by the use of ground-penetrating radar by the Amarna Royal Tombs Project (ARTP), led by Nicholas Reeves, in the autumn of 2000. Unfortunately, no actual tomb was uncovered.
