Langsett is a village and civil parish near Penistone in South Yorkshire. It lies near the southern edge of the Metropolitan Borough of Barnsley and on the edge of the Peak District National Park. At the 2001 census it had a population of 161.
In the early Medieval period, Langsett was known as Penisale. It held a royal charter entitling it to hold a weekly market on Tuesdays and an annual three-day fair, but these were held somewhere in the country rather than in the village itself. The market charter was later used to start a market in Penistone.
A tradition associates the location of Penisale market with a cross near the junction of Cross Lane and Hartcliffe Road. This theory is rejected by Neville T. Sharpe, who holds that this was a wayside cross used as a guide by travellers.
