Monument Creek is a tributary of Spring Brook in Luzerne County and Lackawanna County, in Pennsylvania, in the United States. It is approximately 2.8 mi long and flows through Pittston Township in Luzerne County and Spring Brook Township. The creek is considered to be a High-Quality Coldwater Fishery. It has one named tributary, which is known as Trout Creek. The surficial geology in the vicinity of Monument Creek consists of bedrock, Wisconsinan Till, alluvium, Wisconsinan Ice-Contact Stratified Drift, and fill.

Course
Monument Creek begins in a lake in Pittston Township, Luzerne County. It flows north-northeast for nearly a mile before passing through another pond and turning north. After a few tenths of a mile, it turns north-northeast again and exits Luzerne County. Upon exiting Luzerne County, the creek enters Spring Brook Township, Lackawanna County. It continues flowing north-northeast in a deep valley and re-enters Pittston Township, Luzerne County. It then turns northeast for a few tenths of a mile before turning north-northwest for several tenths of a mile, receiving the tributary Trout Creek from the right and crossing Pennsylvania Route 502 before reaching its confluence with Spring Brook.

Geography and geology
The elevation near the mouth of Monument Creek is 869 ft above sea level. The elevation near the source of the creek is between 1620 and 1640 ft above sea level.

The surficial geology in the vicinity of the lower reaches of Monument Creek mainly consists of alluvium and Wisconsinan Ice-Contact Stratified Drift. However, a glacial or resedimented till known as Wisconsinan Till is also present, as is bedrock consisting of conglomerate, sandstone, and shale. Further upstream, the surficial geology consists almost entirely of Wisconsinan Till and bedrock, but some fill is present as well. Near the headwaters, there are also small patches of alluvium and Wisconsinan Ice-Contact Stratified Drift, as well as one lake.

At one point, Monument Creek flows through an embankment with a depth of approximately 150 ft. A 36-inch (0.9-meter) water main has crossed Monument Creek, elevated at a height of 50 ft above the creek. Mount Pisgah is in the watershed of the creek.

Watershed
Monument Creek is entirely within the United States Geological Survey quadrangle of Avoca. The creek is situated approximately 5 mi from the community of Avoca.
