Ebor Falls, Two-tiered waterfall in Guy Fawkes River National Park, Australia.

Ebor Falls is a two-tiered waterfall in Guy Fawkes River National Park in New South Wales, Australia, where water drops over layers of basalt rock in two separate cascades. Below the falls, the water has carved a deep, forested valley over time.

In 1895, the area around the falls was set aside as a recreation reserve for public use, one of the earlier conservation decisions in the region. It was later incorporated into the broader Guy Fawkes River National Park.

The Gumbaynggirr people, the traditional owners of Ebor Falls, call the falls Martiam, an Aboriginal expression meaning "the great falls". The name is recorded in the sources alongside the English name Ebor Falls.

The first lookout sits on sealed road about 200 metres off Waterfall Way, overlooking the upper falls; the lower falls lie 190 metres further along the walking track. The site has an information display, picnic tables, barbecues and toilets. Camping is not permitted at the falls; the nearest camping is in Cathedral Rock National Park.

The basalt columns over which the water falls were formed by lava flows from an extinct volcano around 19 million years ago. This type of volcanic rock is rarely seen at the surface in this part of Australia.
