The '''Butler Glacier''' ({{Coord|77|24|S|152|42|W|name=Butler Glacier}}) is a broad glacier draining the north side of [Edward VII Peninsula](/source/Edward_VII_Peninsula) in the vicinity of [Clark Peak](/source/Clark_Peak_(Antarctica)), and flowing generally northeastward through the [Alexandra Mountains](/source/Alexandra_Mountains) to its terminus in [Sulzberger Bay](/source/Sulzberger_Bay).{{sfn|Alberts|1995|p=108}}

thumb|Butler Glacier to north of center of map
Butler Glacier flow from west to east through the [Alexandra Mountains](/source/Alexandra_Mountains) from a saddle it shares with [Richter Glacier](/source/Richter_Glacier), which flows northwest. 
It is joined from the south by Larson Glacier, which flows from [La Gorce Peak](/source/La_Gorce_Peak) from a saddle with Blades Glacier.
Towards its mouth it is joined from the south by Dalton Glacier.
The combined streams flow north between the [White Islands](/source/White_Islands) and [Reeves Peninsula](/source/Reeves_Peninsula) to enter [Sulzberger Bay](/source/Sulzberger_Bay).{{sfn|Alexandra Mountains USGS}}
