Hagwilget Peak is the northernmost mountain in the Rocher Déboulé Range in northern British Columbia, Canada.

The 2,076-metre (6,811-foot) mountain summit is conspicuously situated immediately south of Hazelton, British Columbia.

Based on the Köppen climate classification, Hagwilget Peak is located in a subarctic climate zone with cold, snowy winters, and mild summers.

Originally labelled Nil-ke-auda on George Dawson's map for an 1879–80 report for the Geological Survey of Canada, it was later adopted as Awillgate Peak in 1917.

The spelling changed to Hagwilget Peak on 1 February 1963, when officially adopted by the Geographical Names Board of Canada to conform with the modern spelling of the namesake village, Hagwilget.
