Moxlie Creek is a stream in Thurston County in the U.S. state of Washington. It is an Olympian creek originating from artesian springs in Watershed Park. It flows north into the East Bay of Budd Inlet. The creek is piped underground between East Bay and the headwaters, more than one third of its 1.8 mile length. For over 50 years the park groundwater was used to supply the city's drinking water, and waterworks remnants can be seen in the area. Moxlie Creek was named after R. W. Moxlie, an early settler.
