Rock Creek is an 18.9-mile-long (30.4 km) tributary of the Monocacy River in south-central Pennsylvania and serves as the border between Cumberland and Mount Joy townships. Rock Creek was used by the Underground Railroad (at McAllister's Mill, "slaves would slosh through the water to throw off the tracking dogs that were pursuing them") and flows near several Gettysburg Battlefield sites, including Culp's Hill, the Benner Hill artillery location, and Barlow Knoll.

- Blocher's Run is a stream which flows from Oak Ridge (triple watershed point at ) on the Gettysburg Battlefield eastward to the Rock Creek ( ) through and near areas of the Battle of Gettysburg, First Day. During the Battle of Gettysburg Confederate soldiers took cover behind the trees that lined the stream.
- Guinn Run is a stream flowing southeastward from Cemetery Hill past the Gettysburg Museum and Visitor Center to Rock Creek. The stream was bridged by the 1809 Gettysburg and Petersburg Turnpike Company and in the commemorative era by the United States War Department when Hunt and Slocum Avenues were built. A dam was built on Guinn Run to form a pond for Fantasyland, Pennsylvania, through the 1960s and 1970s.
- Spangler Spring Run is a stream which flows from near Culp's Hill to the Rock Creek through Gettysburg Battlefield areas of the Battle of Gettysburg, Second Day, to Rock Creek at .
- Stevens Run (Stevens Creek, Tiber) is a 2.2-mile-long (3.5 km)[verification needed] stream which is a tributary of Rock Creek flowing over the Gettysburg Battlefield and through the borough of Gettysburg, Pennsylvania. Within the borough the stream is in a concrete channel, including a covered portion. From 1884 to 1942, the run was spanned by three bridges of the Round Top Branch railroad. Samuel Gettys' Tavern was located on the south side on the uphill slope of the now-named Stevens Run, and Rock Creek Church was approximately on the north bank of the now-named Carlisle Street and Stevens Run. In 1902, a new bridge was built over the Tiber on Chambersburg Street.
- Winebrenner Run is a stream in Gettysburg, flowing eastward to Rock Creek originally from a Gettys-Black Divide triple point (with Stevens Run & Guinn Run) near Zeigler's Grove. The Confederate military line along the stream was the starting point for the battle of East Cemetery Hill on the second day of the Battle of Gettysburg, and most of the upstream portion of the run was engineered c. 1961 into underground drainage to open flow at the school complex near the Culp Farm at East Confederate Avenue.
- White Run is a stream which flows along East Cavalry Field and is an eponym of the Rock Creek-White Run hospital complex. The run's mouth is at Rock Creek near the Trostle Farm along the Sachs Road, site of a hospital east of Round Top, Pennsylvania.

It was brought back; a few additions were made and only slight repairs have been made since that time. The bridge now has a roadway 16 feet wide. This is to be increased to 20 feet and all abutments and piles are to be reinforced with concrete"

Mr. Henry Schriver lost 150 panels of post and rail fence along the creek by the heavy ice floating against it, and some of the roads were blocked."
