The Bourbeuse River (French for 'muddy') is a river located in east-central
Missouri, in the
Ozarks region, and is one of two major tributaries of the
Meramec River, the other being the
Big River. The Bourbeuse flows to the northeast from its source ( )
 near the locale of
Dillon just northeast of
Franklin counties, where it discharges into the Meramec River near
BOURBEUSE RIVER Latitude and Longitude:
).  The elevation of the river at its source is approximately 1,140 feet (350 m)  above sea level and at its mouth about 463 feet (141 m).  The total length of the river is 154 miles (248 km),  while the airline distance between source and mouth is 53 miles (85 km). The watershed area is 842.9 square miles (2,183 km2).

The river's lower 132 miles (212 km) has permanent flow, but unlike many other Ozark streams of its size, it has a low base flow, due to a paucity of springs feeding it. The river is low-gradient and tends to be more muddy than other Ozark streams. Usually only the lower 108 miles (174 km) are navigable in summer.
The river is highly crooked: one section, near Noser Mill, has 11 miles (18 km) of river between points less than a half mile apart. 107 miles (172 km) of the river are in Franklin County, and only 27 airline miles. Like many other Ozark streams, the Bourbeuse River has entrenched meanders.
Numerous fords are named on this river, compared to other rivers in the state. The gravel riverbeds, low average river flow, and lack of sufficient bridges both allow and require the use of natural river crossings.
