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 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 () 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 at a creek named Wayna Chullkani (Huayna Chullcani).
