Little Roaring Creek is a tributary of the Susquehanna River in Montour County and Northumberland County, in Pennsylvania, in the United States. It is approximately 4.4miles long and flows through Mayberry Township, Montour County and Rush Township, Northumberland County. The watershed of the creek has an area of 5.98sqmi. The creek is considered to be a coldwater fishery and a migratory fishery. At least two mills historically existed on it. Additionally, a number of bridges cross the creek.
Little Roaring Creek begins on a hill in the southwestern corner of Mayberry Township, Montour County. It flows west for a short distance to the border between Mayberry Township, Montour County and Rush Township, Northumberland County. At this point, the creek turns north-northwest and flows closely parallel to the border between Montour County and Northumberland County and roughly parallel to State Route 2119. The creek flows through a valley for several miles, eventually turning north and slightly east. It eventually leaves its valley and almost immediately reaches its confluence with the Susquehanna River.
Little Roaring Creek joins the Susquehanna River 140.88miles upstream of its mouth.
The elevation near the mouth of Little Roaring Creek is 440feet above sea level. The elevation of the source of the creek is between 980feet and 1000feet above sea level.
Little Roaring Creek forms part of the border between Montour County and Northumberland County. The creek enters the Susquehanna River on the river's left bank. There are glacial drift deposits at the headwaters of the creek. The drift is fairly thick and have been described as "exceptionally heavy". Additionally, a moraine is present. The glacial drift is at an elevation of nearly 1000feet above sea level.
The watershed of Little Roaring Creek has an area of 5.98sqmi. The creek drains a portion of Montour County's southern panhandle. It is in the eastern portion of Northumberland County and is in the United States Geological Survey quadrangle of Danville.

Little Roaring Creek formed a portion of a township border as early as 1788. At some point in the past, R. Davidson constructed a sawmill on the creek. It was abandoned some time before 1915. A gristmill owned by Jacob Swank also historically existed on the creek. It was still operational as late as 1915, when it was owned by S. Cromley. James Bird purchased a tract of land on the creek in the 1700s or 1800s and his son Ziba farmed the tract.
A concrete stringer bridge crosses Little Roaring Creek 4miles north of Elysburg. This bridge is 33.1feet long. Another bridge crosses the creek 4miles. This bridge is a concrete tee beam bridge that is 45.9feet long. It was built in 1922 and repaired in 1978. Another concrete tee beam bridge was built over the creek in 1928 and is 23feet long. A prestressed box beam bridge was built in 1940 and repaired in 1994 and is 38.1feet long. A concrete channel beam bridge was built over the creek in 1954 and repaired in 2012. This bridge is 24.9feet long.
A bridge carrying Route 2001 over Little Roaring Creek received a weight restriction in 2013.

The creek was added to the Geographic Names Information System on August 2, 1979.
