Brush Prairie was named for the brush near the original town site. There is still a post office called Brush Prairie that has been in operation since 1871. The area is located southwest of the center of Clark County bordered by Meadow Glade and Battle Ground to the north, Hockinson to the east, Orchards and Five Corners to the south, and Barberton to the west. State Route 503 passes through the community from north to south. Brush Prairie is a growing area that includes Prairie High School (PHS), which opened in 1979.
