town, southwestern Manitoba, Canada. It lies along the Vermilion River just west of Dauphin Lake, 201 miles (323 km) by road northwest of Winnipeg. The French trader and explorer La Vérendrye visited the lake in 1739 and named it for the dauphin of France. One of the two settlements that developed in the area after 1882 took the same name. The settlements, Dauphin and Gartmore, merged in 1896, when the Lake Manitoba Railway reached the site. The town became a service centre for a large agricultural region and the area headquarters for the Canadian National Railway, a major employer. It is also a tourist base for nearby Riding Mountain National Park (south) and Duck Mountain Provincial Park and Forest (northwest) and hosts Canada's annual National Ukrainian Festival (August). Inc. village, 1898; town, 1901. Pop. (2001) 8,085.

The county was created in 1785; its name was derived from the title of the eldest son of the king of France. Harrisburg, the county seat (1785) and state capital (1812), became a major transportation hub with the advent of canal and rail travel, particularly by the Pennsylvania Canal (1834) and the Pennsylvania Railroad (Pennsylvania Railroad Company)'s main line to Pittsburgh (1847).

The nuclear power station at Three Mile Island, in the Susquehanna near Harrisburg, was the site of a serious accident in March 1979.

Other communities include Middletown, Steelton, Hummelstown, and Paxtang, which was once an Indian village. In addition to governmental activities and other services (health care and tourism), the economy is based on steel mills and manufacturing, particularly food products, industrial machinery, and transportation equipment.
