Huandoy (in hispanicized spelling), Wantuy (Quechua for to transfer, to transpose, to carry, to carry a heavy load) or Tullparahu (Quechua tullpa rustic cooking-fire, stove, rahu snow, ice, mountain with snow, hispanicized Tullparaju) is a mountain located in the Ancash Region of Peru. It is the second-tallest peak of the Cordillera Blanca section of the Andes, after Nevado Huascarán. These two peaks are rather nearby, separated only by the Llankanuku ravine with its Llankanuku Lakes (3,846 m).
It is a snow-capped mountain with four peaks, the tallest of which is 6,395 m arranged in the form of a fireplace. The four peaks are each over 6,000 m, and are:
- Huandoy Peak (6,395 m)
- Huandoy-West (6,356 m)
- Huandoy-South (6,160 m)
- Huandoy-East (6,070 m)
It was first climbed in 1932 by a German party. The ascent from the Llankanuku Lakes was first climbed in 1976.
It is part of Huascarán National Park.
