Abiel Peak is a 5,365 ft (1,640 m) mountain summit located in eastern King County of Washington state.

[4] It is set 1,000 feet west of the crest of the Cascade Range, on land managed by Mount Baker-Snoqualmie National Forest.

Precipitation runoff from the south side of the mountain drains into headwaters of Tinkham Creek which is a tributary of the North Fork Cedar River, whereas the north side of the mountain drains into Annette Lake, thence the South Fork Snoqualmie River via Humpback Creek.

Topographic relief is significant as the north aspect rises 1,860 feet (570 meters) above Annette Lake in one-half mile.

Abiel Peak is located in the marine west coast climate zone of western North America.
