Wondabyne is a suburb located in the Central Coast region of New South Wales, Australia, as part of the City of Gosford local government area.

The suburb contains Wondabyne railway station, which is serviced by CityRail services to Wyong on the Main North railway line and is adjacent to a wharf on Mullet Creek, a tributary estuary of the Hawkesbury River. The train station has a very short platform, only long enough to hold around one train door.

Due to the rugged terrain of the area, Wondabyne station is the only station in Australia that does not have vehicular access. The station relies on water access for its existence.

Just north of the railway station by the water is a 70 acre tract of land owned by Gosford Quarries that contains a sandstone quarry. Stone is cut from the quarry periodically for restoration works on Sydney city buildings that were originally constructed many years ago from Wondabyne sandstone. In 2000, the quarry was brought back into operation to provide stone for the two spires of St Mary's Cathedral, Sydney. The spires now complete the construction of the cathedral which was started in 1868.

Wondabyne is a popular starting point for bushwalks into the surrounding Brisbane Water National Park. Destinations include Pindar Cave, Kariong Brook and Wondabyne Trig - the latter offers extensive views of the surrounding area. Walking trails also join the Great North Walk (which stretches from Sydney to Newcastle) for more extensive trips.
