Thokcha (Tibetan: ཐོག་ལྕགས, Wylie: thog lcags;^[2] also alternatively Tibetan: གནམ་ལྕགས, Wylie: gnam lcags^[3]) are Tibetan amulets which are said to have fallen from the sky in traditional tibetan folklore.^[4] These are traditionally believed to contain a magical, protective power comparable to Tibetan dzi beads. Most thokcha are made of a copper alloy.^{[5][failed verification]}

The use of meteoric iron has been common throughout the history of ferrous metallurgy. Historically, thokcha were prized for the metallurgical fabrication of weapons, musical instruments, and sacred tools, such as the phurba. Thokcha are an auspicious addition in the metallurgical fabrication of sacred objects cast from panchaloha.

Writer Robert Beer^[6] regards meteoric iron as "the supreme substance for forging the physical representation of the vajra or other iron weapons." It was believed that these amulets had been tempered by the celestial gods before falling to Earth. Beer describes the metal falling from space as a metaphor for "the indivisibility of form and emptiness."^[7] Many meteorite fragments can be found in Tibet due to its high altitude and open landscape.^[7]
