Dalmatia Creek is a tributary of the Susquehanna River in Northumberland County, Pennsylvania, in the United States. It is approximately 2.8 miles (4.5 km) long and flows through Lower Mahanoy Township. The watershed of the creek has an area of 2.80 square miles (7.3 km2). The creek has no named tributaries, but several unnamed ones. Both it and its tributaries are designated as impaired waterbodies due to sedimentation/siltation from crop-related agriculture and vegetation removal. Streambank erosion also occurs in the watershed. The creek is in the Ridge and Valley physiographic province.
The main land use in the watershed of Dalmatia Creek is agricultural land, but forested land, low-intensity development, and transitional land are also present. The creek experienced flooding during Tropical Storm Agnes in 1972. A bridge carrying Pennsylvania Route 147 has been constructed across it in Dalmatia. The drainage basin of the creek is designated as a Warmwater Fishery and a Migratory Fishery.
Dalmatia Creek begins at the base of a mountain in Lower Mahanoy Township. It flows north-northwest for a few tenths of a mile, entering a valley. The creek then flows west-southwest for a few tenths of a mile, receiving an unnamed tributary from the before turning west. After several tenths of a mile, it turns west-southwest again for several tenths of a mile, receiving two more unnamed tributaries from the left, one of them extremely short. The creek then turns west for a few tenths of a mile, receiving another two unnamed tributaries from the left, before turning west-southwest. After several tenths of a mile, it turns west for a few tenths of a mile, receiving two more unnamed tributaries from the left and entering the census-designated place of Dalmatia. Here, the creek turns northwest for a few tenths of a mile before turning west. A short distance further downstream, it crosses Pennsylvania Route 147 and reaches its confluence with the Susquehanna River.
