The 1929 Murchison earthquake occurred at 10:17 am on 17 June. It struck the Murchison region of the South Island, with an estimated magnitude of 7.3, and was felt throughout New Zealand. There were 17 deaths, mostly as a result of landslides triggered by the earthquake. The rumbling sound of the earthquake was loud enough to be heard at New Plymouth, more than 250 km (155 mi) away.

Murchison is a town in the Tasman Region of the South Island of New Zealand. It is near the western end of the "Four Rivers Plain", at the confluence of the Buller River and the Matakitaki River. The other two rivers are the Mangles River, and the Matiri River.

It is a rural service town for the surrounding mixed farming district, approximately halfway between Westport and Nelson. Murchison was named after the Scottish geologist Roderick Murchison, one of the founders of the Royal Geographical Society.
