Pacific Peak, elevation 13,957 ft (4,254 m), is a summit in the Mosquito Range of central Colorado. The peak is southwest of Breckenridge in the Arapaho National Forest. Its long east ridge is prominently visible across the valley to the north when hiking Quandary Peak, a popular 14er in Colorado. It is often hiked together with nearby Atlantic Peak. Pacific Tarn, the highest officially named lake in the United States, lies high on the eastern flank of the peak.
