Course
Leslie Creek begins near Wolf Hill in New Milford Township. It flows south for several tenths of a mile, passing through an unnamed pond, entering Harford Township, and passing through another unnamed pond. The creek then turns east before turning south again for a short distance, entering Tingley Lake, where it receives an unnamed tributary from the right. The creek then flows southeast for several tenths of a mile, receiving one unnamed tributary from the right and one from the left before entering a wetland. Here, it turns south for several tenths of a mile before turning south-southeast. After a few tenths of a mile, the creek receives an unnamed tributary from the right and crosses Pennsylvania Route 547. It continues flowing south-southeast for several tenths of a mile before turning south, receiving another unnamed tributary from the right, and turning southeast. After a few tenths of a mile, the creek turns south-southeast for a few tenths of a mile before reaching the end of its valley and turning east. A short distance further downstream, the creek reaches its confluence with Nine Partners Creek.

History
Leslie Creek was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1179216.

According to several local residents in the 1960s, an official 1932 map of the area showed Leslie Creek flowing too far to the east. The creek was described as flowing through the community of Harford in several old deeds and documents.

By 2005, the Pennsylvania Department of Transportation had made plans to reconstruct a bridge carrying Pennsylvania Route 547/Fair Hill Road over Leslie Creek. The bridge, whose purpose was to allow access to the village of Harford, was deemed structurally deficient and functionally obsolete, but contributed to the Harford Historic District.
