Bombus sylvicola is a species of bumblebee native to North America. It occurs throughout most of Canada, its distribution extending into Alaska and the western contiguous United States. In the southernmost extent of its range in California it occurs only at elevation. It is known commonly as the forest bumblebee. This species is very similar to the black-tailed bumblebee (B. melanopygus), the two sometimes having nearly identical color patterns.
