The Hook Norton ironstone quarries (Earl of Dudley) were ironstone quarries at Hook Norton, Oxfordshire, England, in operation from 1901 to 1916 Located to the south of Hook Norton, the system included a calcining kiln and a variety of cable-hauled tramways and inclines.

History
Land was purchased by the Earl of Dudley in 1898 and the quarries are believed to have opened in 1901 Initially there were two quarries, Grounds Quarry near Hook Norton Grounds Farm and another on the opposite side of the Banbury and Cheltenham Railway viaduct. Tonks suggests that this second quarry was probably called Archill. When the Archill quarry was exhausted, a third one was opened. This was Beanacre Quarry which adjoined Brymbo's Park Farm quarry. The ore was sent to the Earl of Dudley's Round Oak Ironworks. There were several temporary closures during the period of operation and working finally ceased in April 1916 and the plant was dismantled in 1920.

Description
A straight double-track tramway ran along the valley floor connecting Grounds and Archill quarries. Full trucks used one track and empties the other. No locomotives were used, all operation was by cable-haulage. Just east of the viaduct was a calcining kiln operated on the batch system, that is to say it was filled, burnt and then emptied. Turntables on the tramway allowed tubs of ironstone to be hauled up a ramp supported by trestles and tipped into the kiln.

A standard-gauge siding curved off the Banbury-Cheltenham railway to serve the quarries but since this was high above the valley floor two inclines were provided to link the siding to the kiln. One incline was used to raise tubs of ore to the siding, this was powered by a two-cylinder engine near the kiln. The other incline was used to deliver coal and was worked by gravity.

When Beanacre quarry was opened, the tramway was extended at an angle to the existing line. A metal plate was provided to turn the wagons and the cable “was presumably taken round a pulley”
