Coal Creek is a creek in Bellevue, Washington, USA, on Seattle's Eastside. It is named for the coal mining industry prominent in the area in the 19th century. There is a popular trail which parallels the creek, allowing views of defunct coal mining equipment and even some bits of coal sitting on the ground in spots.
The source of Coal Creek is 1,400 feet above sea level on Cougar Mountain. It flows approximately 7 miles to the northwest, emptying into Lake Washington at Newport Shores.
