Totley is a suburb on the extreme southwest of the City of Sheffield, in South Yorkshire, England. Lying in the historic county boundaries of Derbyshire, Totley was amalgamated into the city of Sheffield in 1935, and is today part of the Dore and Totley electoral ward in the city, though it remains close to the contemporary county boundary of Derbyshire. Totley had a population of 7,963 in 2011. Totley was shown at the 2011 census as being part of the ward of Dore and Totley.
Totley was mentioned in the Domesday Book of 1086 as Totinglee, the name meaning a forest clearing belonging to Tota (probably the Saxon lord). Totley Hall, built in 1623 and enlarged in the 19th century, was converted to a teacher training college in the 1950s and was latterly part of Sheffield Hallam University.
Through the district run the Totley Brook and the Old Hay Brook, which are the two sources of the River Sheaf. Totley also lends its name to Totley Tunnel, the longest underland rail tunnel in the United Kingdom. This takes the Sheffield to Manchester line from Totley underneath the Totley Moor to Grindleford in Derbyshire.
