The Karangahake Gorge lies between the Coromandel and Kaimai Ranges at the southern end of the Coromandel Peninsula in New Zealand's North Island. A sharply winding canyon, it was formed by the Ohinemuri River.
The East Coast Main Trunk Railway used to run through the gorge. Part of the line, including a 1000-metre tunnel, is now a walkway. The railhead at the Waikino end of the Gorge still exists, preserved as part of the Goldfields Railway to Waihi.
