The Little Chilliwack River is a small river in Whatcom County, Washington. It is a tributary of the Chilliwack River, entering the river just below the United States/Canada Border.
The river originates at a ridge between it and Silesia Creek. It flows just over 7 miles northeast from there to its confluence with the Chilliwack on the opposite side of the river from a trail leading up the Chilliwack. The Little Fork merges with it just under 2 km above its mouth.
The Little Fork Little Chilliwack River starts at the base of Copper Mountain. It flows about 4 ½ km northeast as well, merging with the main fork about 2 km upstream from the river’s mouth.
