Dinnington Main Colliery was a coal mine situated in the village of Dinnington, near Rotherham, South Yorkshire, England.
Until the coming of the colliery Dinnington was a mainly agricultural village with a small amount of quarrying in the area.
In 1899 preparations were being made by the Sheffield Coal Company to sink a new colliery at Dinnington. The company did not have the resources to complete the work and entered into a partnership with the Sheepbridge Coal and Iron Co and this joint company, the Dinnington Main Colliery Company, came into being in 1900. The colliery commenced sinking in 1902 and reached the Barnsley seam of coal in the summer of 1904. The first coal was drawn to the surface the following year which is also when the mine gained its second shaft.
Rail connection for the colliery was eventually made by the South Yorkshire Joint Railway, a five way joint line with connections to ports and towns in the area and beyond.
At the time of the 1946 nationalisation of the coal industry the colliery was in the hands of Amalgamated Denaby Collieries, based at Denaby Main, near Doncaster. Following nationalisation the colliery became part of the National Coal Board.
The colliery was closed in 1992.
