White Rock Creek is a 30 miles (48 km) creek occupying a chain of four sub-watersheds within the Trinity River watershed. From its source near Frisco, Texas at 33°07′54″N 96°46′50″W / 33.13167°N 96.78056°W / 33.13167; -96.78056, this creek runs south-by-south-east through suburban Dallas for 23.5 miles (37.8 km) where it widens into White Rock Lake, then continues south for another 8 miles (13 km) to its mouth on the East Fork of the Trinity River, of which it is a major tributary.

Despite running through one of the most populous areas of Texas, and flowing under many major roads and highways, its banks remain heavily wooded and undisturbed in many places and many local parks are situated within its watershed, which is generally considered to extend 2 miles (3.2 km) to 2.5 miles (4.0 km) either side of its path.

At least eight "White Rock Creeks" exist in the Dallas metro area; this article describes the White Rock Creek of Collin County and Dallas County, Texas which feeds into White Rock Lake.
