The Andean squirrel (Sciurus pucheranii) is a tree squirrel endemic to Colombia. The Andean squirrel is a typical tree squirrel, in its general proportions resembling the Eastern grey squirrel of North America. However, it is much smaller, with a body length of only about 14 centimetres (5.5 in), and a 12 to 16 centimetres (4.7 to 6.3 in) tail. Although there are few records of its weight, it appears to be generally between about 100 and 140 grams (3.5 and 4.9 oz).
