Bonpas Creek is a tributary of the Wabash River in Illinois. It joins the Wabash near Grayville, Illinois. In the last 2 miles (3 km) of its watercourse, it occupies part of a former Wabash oxbow bend.
The name is derived from the early French settlers of the Illinois Country. The name probably means "good steps" or "good path". The name is pronounced locally as "Bom Paw". The nearby town of Bone Gap was named in reference to the creek. The early settlers, mainly from Kentucky, understood the name of the creek to refer to a "pass", in the sense of a mountain pass, and then substituted the Kentucky equivalent, "gap", as in Cumberland Gap.
Other locals such as those in nearby villages of BoneGap, Browns, Bellmont and southern Illinois communities pronounce the name as Bum-paw, with the emphasis on the Bum. This pronunciation, though not completely true to the original French, is still much closer to the correct way to say the name. A legend about how Bum-paw got its name tells of an early pioneer father traveling in his wagon across the creek with his young son from their cabin to a nearby settlement. The father it is told gets his wagon and team of horses stuck in the creek. As he wades into the water it is said the young son is saying, "Bum-paw, Bum-paw" as the father pulls the team of horses and wagon across the creek.
