Hunlock Creek (also known as Hunlocks Creek) is a tributary of the Susquehanna River in Luzerne County, Pennsylvania, in the United States. It is approximately 7.8miles long and flows through Lehman Township and Hunlock Township. The watershed of the creek has an area of 32.5sqmi and is situated in northwestern Luzerne County. It has one named tributary, which is known as Roaring Brook, and a number of unnamed and unofficially named tributaries, such as "West Branch Hunlock Creek".
Hunlock Creek is designated as a coldwater fishery and a migratory fishery, and part of it is inhabited by wild trout. The annual rate of precipitation in the watershed is 35inchesto45inchesin (toin). Rock formations consisting of sandstone and shale are common in the vicinity of the creek. A number of bridges have been built over the creek and it was the site of a furnace in the 1800s. An area listed on the Luzerne County Natural Areas Inventory is located in the creek's watershed.
Hunlock Creek begins in a valley in Lehman Township, a short distance northwest of Lake Silkworth. It flows south for several tenths of a mile before turning south-southeast for a similar distance and receiving an unnamed tributary from the left. The creek then turns south for approximately half a mile, exiting Lehman Township and entering Hunlock Township. It continues flowing generally southwards for more than a mile and its valley widens considerably. The creek receives another unnamed tributary from the left before its valley narrows again and it turns southwest. After approximately a mile, it receives Roaring Brook, its only named tributary, from the right. The creek then turns south-southeast for a few miles, receiving one unnamed tributary from the left and one from the right. The creek turns east-northeast for several tenths of a mile and receives another unnamed tributary from the left. It then turns southeast, passing through a water gap and crossing US Route 11 in the village of Hunlock Creek. A short distance further downstream, the creek reaches its confluence with the Susquehanna River.
Hunlock Creek joins the Susquehanna River 178.21miles upriver of its mouth.
Hunlock Creek has one named tributary, which is known as Roaring Brook. Roaring Brook joins Hunlock Creek 3.99miles upstream of its mouth. Its watershed has an area of 6.17sqmi. Hunlock Creek also has an unnamed tributary that is unofficially known as "West Branch Hunlock Creek". This tributary is approximately 7.6miles long. Additionally, it has a number of other unnamed tributaries.
Hunlock Creek is not designated as an impaired waterbody, meaning that it attains standards for water quality.

At the confluence of one of its tributaries with the main stem, the discharge of Hunlock Creek has a 10 percent chance of peaking at 2100cuft/s in any given year. It has a 2 percent chance of peaking at 4300cuft/s, a 1 percent chance of peaking at 5650cuft/s, and a 0.2 percent chance of peaking at 10800cuft/s.
The peak annual discharge of Hunlock Creek at the confluence of another one of its tributaries with the main stem has a 10 percent chance of reaching 1460cuft/s. The discharge has a 2 percent chance of reaching 3050cuft/s and a 1 percent chance of reaching 4050cuft/s. It has a 0.2 percent chance of reaching 7900cuft/s.

A high ridge runs from near Hunlock Creek westward to the Shickshinny Gap. This ridge is known as Shickshinny Mountain and is made from Pocono beds. Green sandstone and red shale occur along the creek. A sandstone formation containing red quartz pebbles also occurs in the area and at one point forms a 30feet high cliff along the creek. Additionally, shale of the Mauch Chunk Formation can be found in the vicinity of the creek.
Drift heaps cover the old channel of Hunlock Creek.
A 1921 report by the Water Supply Commission of Pennsylvania described the topography of the watershed of Hunlock Creek as "rough and hilly". The creek cuts through a mountain range in its lower reaches. Swamps and glacial lakes occur in the watershed. The channel of the creek is sinuous and cuts through rock formations consisting of sandstone and shale.

Two two-span concrete tee beam bridges carrying State Route 4016 were built over Hunlock Creek in Hunlock Township in 1925. The bridges are 65.9feet and 58.1feet long. Both bridges underwent repair work in 1983. A concrete slab bridge carrying Pritchards Road was built over the creek in 1937. This bridge is 23feet long. A masonry arch bridge carrying State Route 4005/Cragle Road over the creek in Hunlock Township was built in 1938 and is 34.1feet long.

The entire drainage basin of Hunlock Creek is classified as a coldwater fishery and a migratory fishery in Chapter 93.9 of the Pennsylvania Code. Wild trout naturally reproduce in the creek from T-534 downstream to its mouth. This stretch is 3.9miles long. They also naturally reproduce in the tributary Roaring Brook and in the unofficially named tributary West Branch Hunlock Creek.
The Shickshinny Mountain Slopes, which are listed as a Locally Significant Area in the Luzerne County Natural Areas Inventory, are located in the watershed of Hunlock Creek in Plymouth Township. These slopes are on the northern side of Shickshinny Mountain and contain second-growth northern hardwood forests and some rock outcroppings with small seeps. The area contains a large number of wildflower species and some rare plants. The main tree species in this area include American basswood, sugar maple, white ash, white oak, black cherry, and eastern hemlock.
