The parish of South Killingholme extends from the
Humber Estuary foreshore roughly southwest through the village of South Killingholme to a boundary near
Ulceby railway station; the parish is roughly long (north-west to south-east) and wide. The parish had a population of 1,047 at the 2001 census, and at the 2011 census a population of 1,108. The southeastern and southern sides of the parish forms a boundary with the parishes of
Immingham and
Habrough and with the administrative county of
North East Lincolnshire, following the line of the main drain leading to South Killingholme Haven. The southwestern edge of the parish extends as far as, and included
Ulceby railway station, east of the village of
Ulceby, where the boundary is with the parishes of
Brocklesby and Ulceby, much of the boundary following the line of the canalized Skitter Beck. The northwestern boundary is entirely with the parish of
North Killingholme, running southeast–northwest; from the southern part along the West Mere Middle Road, then bisecting the
Lindsey Oil Refinery, and exiting the bank of the Humber Estuary halfway between north and south Killingholme havens. The parish is low lying rising from less than above sea level near the Humber bank, to a peak of above sea level in the southwest part of the parish, south of the village. Half of the parish is in agricultural use, primarily farming but including some plantations, the land is drained by man made ditches. The only human habitation in the parish of any note is the village of South Killingholme, near to the centre of the parish. The remainder of the parish is used for industrial and logistical purposes – northeast of the village is the
Humber Oil Refinery, with the Lindsey Oil Refinery to the north also partially in the parish. Near the banks of the Humber the development of the
Port of Immingham estate extends into the parish, specifically the western part of the
Immingham Bulk Terminal, known as the
Humber International Terminal; and the
Immingham Gas Terminal; the freight branch line to the docks (formerly the
Humber Commercial Railway) runs through the parish from a junction near Ulceby station. To the northwest along the banks is the Killingholme gas jetty, and an associated storage facility. Three lighthouses, all constructed in the 19th century, are located on the Humber bank near to the oil storage terminal. The
A1077 /
A160 passes through the parish from a junction with the
A180 passing through the village, and connecting to Immingham Dock. ==Lighthouses==
