Ollerton is a town in Nottinghamshire, England, on the edge of Sherwood Forest in the area known as the Dukeries. It forms part of the civil parish of Ollerton and Boughton. Formerly rural, its main industry became coal mining from the 1920s onwards. The town expanded greatly during the 1960s and 1970s. A miner died in a demonstration at the mine during the miners' strike in 1984. Ollerton features in a connected song by Australian singer Darren Hayes called "A Hundred Challenging Things A Boy Can Do" on his 2007 album, This Delicate Thing We've Made. The mine finally closed in 1994. Subsequently, the land around the mine has been reclaimed and is to be redeveloped as an ecologically sustainable "village".
In the original, old part of the former village Ollerton Watermill was built in 1713 on the River Maun. It was worked commercially until 1984. It was restored in 1993. Ollerton Town has a local football team, Ollerton Town F.C.
Ollerton is the birthplace of Tim Flear MVO (Royal Victorian Order), career member of the British diplomatic service and a former HM Consul-General in the city of Rio de Janeiro in Brazil, Flear's father was the local butcher;
There is some ambition to re-instate passenger train services to the town utilising the current freight only line from Shirebrook on the Nottingham-Worksop route.
