Conewago Creek is a 23.0-mile-long (37.0 km)tributary of the Susquehanna River in Lebanon, Dauphin, and Lancaster counties in Pennsylvania in the United States. The source is at an elevation of 1,100 feet (340 m) at Mount Gretna Heights in Lebanon County. The mouth is the confluence with the Susquehanna River at an elevation of 261 feet (80 m) at the border of Dauphin and Lancaster counties, just south of Three Mile Island in the river and just north of the unincorporated village of Falmouth in Conoy Township, Lancaster County.
The name of the creek comes from the Lenape, meaning "at the rapids". The rapids are the Conewago Falls in the Susquehanna River, which also give their name to the other Conewago Creek, whose mouth is on the west bank of the Susquehanna River in York County, only 1.6 miles (2.6 km) south of the mouth of this Conewago Creek.
Conewago Creek flows generally southwest its entire length. The source is in Lebanon County in West Cornwall Township near the census-designated place of Mount Gretna Heights. It then flows through the borough of Mount Gretna and into South Londonderry Township and the census-designated place of Timber Hills. A small southern portion of South Annville Township is also in the watershed.
