Eagle Creek is a census-designated place (CDP) in Centre County, Pennsylvania, United States. It was first listed as a CDP prior to the 2020 census.
The CDP is in south-central Centre County, in the southern part of Union Township. It is bordered to the northeast by the borough of Unionville and to the southeast by Julian. Eagle Creek sits in the valley of Bald Eagle Creek, a northeastward-flowing tributary of the West Branch Susquehanna River. Dicks Run flows through the CDP from northwest to southeast to join Bald Eagle Creek at the southern border of the CDP. Bald Eagle Mountain rises above the community on the south side of Bald Eagle Creek.
U.S. Route 220 Alternate runs through the CDP, following the Bald Eagle Creek valley. It leads northeast through Unionville 7miles to Interstate 80 at Milesburg and southwest 11miles to Port Matilda.
The CDP is highlighted by the junction of South Eagle Valley Road and Dix Run Road, which follows Dicks Run, then continues to Beaver Road north of Julian.
