Skelsmergh is a small village and former civil parish, now in the parish of Skelsmergh and Scalthwaiterigg, in South Lakeland in rural Cumbria, England, about 4 miles north of Kendal, on the A6 road.
St. John the Baptist Church at Skelsmergh dates from about 1871 and was built by Joseph Bintley, a Westmorland architect. Skelsmergh Hall incorporates a pele tower, probably built in 1425, with late 16th century and early 17th century additions. The tower is now an outbuilding. The River Sprint runs alongside the village and is "one of the quietest of the Lake District's valleys".
Skelsmergh had a population of 303 according to the 2011 census. When comparing this to the total population of the village 50 years earlier, in 1961, it is clear that the population has seen an increase from 250 in 1961.

"Skelsmergh, township, in par. and 2 miles NE. of Kendal, Westmorland, 2093 ac., pop. 367."
Skelsmergh had a population of 303 according to the 2011 census. It previously had a joint parish council with the adjacent parish of Scalthwaiterigg.
