Andrews Glacier is an alpine glacier in a cirque below Otis Peak ({{convert|12486|ft|abbr=on}}) in Rocky Mountain National Park in the U.S. state of Colorado.{{Cite map|publisher=TopoQwest (United States Geological Survey Maps)|title=McHenrys Peak, CO|url=http://www.topoquest.com/map.php?lat=40.28748&lon=-105.68389&datum=nad83&zoom=4|access-date=2012-08-18}} The glacier extends from Andrews Pass at nearly {{convert|12000|to|11700|ft}} with some perennial snow extending to Andrews Tarn, a small proglacial lake. When images of the glacier taken in the early 1900s are compared with those of the early 2000s, Andrews Glacier is showing a negative glacier mass balance which indicates the glacier is retreating.{{cite journal|last=Hoffman|first=Matthew|author2=Andrew Fountain|author3=Jonathan Achuff|title=20th-century variations in area of cirque glaciers and glacierets, Rocky Mountain National Park, Rocky Mountains, Colorado, USA|journal=Annals of Glaciology|year=2007|volume=46|pages=349–354|url=http://glaciers.pdx.edu/fountain/MyPapers/HoffmanEtAl2007_FrontRangeCOglaciers.pdf|access-date=2012-08-18|doi=10.3189/172756407782871233|s2cid=28944236|doi-access=free}}
