South Dakota Highway 1804 (SD 1804) is a 126.745-mile-long (203.976 km) state highway in the U.S. state of South Dakota.
It consists of four disconnected segments. The southernmost segment is in the central part of Charles Mix County. It travels 3.792 miles (6.103 km) from the shore of the Missouri River south of Geddes north to an intersection with SD 50 also south of Geddes. The second segment is in the northwestern part of Charles Mix County. It travels 8.039 miles (12.938 km) from an intersection with 282nd Street southwest of Platte to an intersection with SD 44/SD 50 southeast of Academy. The third segment is in the central part of the state. It travels 57.014 miles (91.755 km) from an intersection with US 14/US 83 in Pierre north to an intersection with 160th Street north-northeast of Forest City. The fourth segment, which is the longest segment, travels 57.900 miles (93.181 km) from a continuation of 135th Street south-southeast of Glenham northward to the North Dakota state line. Here, it intersects 102nd Street and continues as ND 1804.
