Walnut Creek is a 17.93 mi (28.86 km) long 4th order tributary to the Neuse River in Wake County. Its source is a small pond near WakeMed Soccer Park in Cary, and it flows generally eastward through several small reservoirs, including Lake Cramer in Cary as well as Lake Johnson and Lake Raleigh in Raleigh, before reaching its confluence with the Neuse just south of Poole Road in East Raleigh. The course of the creek closely parallels Interstate 40, running mostly along the north side of the freeway.

The Walnut Creek Trail, a branch of the Capital Area Greenway, follows the length of Walnut Creek from Lake Johnson to its confluence, and is the second longest trail in the Greenway System. A large swampy wetland (which has been partially reclaimed by urban development), occupies the area around the last several miles of the creek; the Walnut Creek Wetland Center, operated by Raleigh Parks and Recreation, is dedicated to the study and preservation of the wetlands. The Coastal Credit Union Music Park, commonly known by its original name of Walnut Creek Amphitheater, is located near the wetland area near where the creek passes under the I-40/I-440 interchange.
