Wayna Chullunkhäni (Aymara wayna young, chullunkhä ('ä' stands for a long 'a') icicle, -ni a suffix to indicate ownership, meaning "Young Chullunkhäni" or literally "the young one with icicles", Hispanicized spelling Huayna Chulluncani, also Huayna Chullcani) is a 4,736-metre-high (15,538 ft) mountain in the Cordillera Occidental in the Andes of Bolivia. It is located in the Oruro Department, Sajama Province, Turco Municipality.

The name of this mountain - where wayna is sometimes used in the Andes region as an attribute for a neighboring lower mountain - might refer to the Chullkani volcano (5,032 m (16,509 ft)) west of it which possibly erroneously received that name instead of 'Chullunkhäni'.

Another mountain named Wayna Chullunkhäni, also spelled (Huayna Chuluncani), lies northwest of Chullkani at 18°14′57″S 68°51′22″W / 18.24917°S 68.85611°W / -18.24917; -68.85611 at a creek named Wayna Chullkani (Huayna Chullcani).
