Newnes (/nuːnz/), an abandoned oil shale mining site of the Wolgan Valley, is located in the Central Tablelands region of New South Wales, Australia.

A major oil shale mine with two headings was started on the north side of the Wolgan River, opposite the works.

Although construction of a tunnel linking the Wolgan Valley with the Capertee was proposed on numerous subsequent occasions, it was to remain an elusive dream.

The main works site was established in a sweeping bend on the south bank of the Wolgan River and extending up the adjacent talus hillside.

These works consisted of retorts, various distillation areas, oil storage tanks and washers, plant for the refining of the various finished products, a power station, workshops, etc., with provision for future expansion.

Originally known as Wolgan, it was renamed Newnes—after Sir George Newnes, the chairman of the Commonwealth Oil Corporation at the time—in early 1907.

The Newnes Hotel functioned successfully for some time, although business was affected when mining operations were shifted to Glen Davis, further north in the Capertee Valley.
