Swale Brook is a tributary of Tunkhannock Creek in Wyoming County, Pennsylvania, in the United States.

A short distance further downstream, the stream crosses US Route 6 and reaches its confluence with Tunkhannock Creek.

[1] Swale Brook joins Tunkhannock Creek 0.64 miles (1.03 km) upstream of its mouth.

[3] The Tunkhannock Area School District once applied for and/or received a permit to discharge stormwater into the stream during construction activities.

[7] The surficial geology in the vicinity of the lower and middle reaches of Swale Brook consists of alluvium, Wisconsinan Outwash, Wisconsinan Ice-Contact Stratified Drift, and alluvial terrace.

[10] Swale Brook was entered into the Geographic Names Information System on August 2, 1979.

[6] This variant name appears in Israel C. White's 1883 book The geology of the North Branch Susquehanna River Region in the six counties of Wyoming, Lackawanna, Luzerne, Columbia, Montour and Northumberland.

Shortly before 1906, a canning factory on the stream closed; in that year the Pennsylvania Witch Hazel Company opened at the site.

[13] The Federal Emergency Management Agency once purchased some homes along the stream as part of a buyout program.
