Mathinna Falls is a multi-tiered waterfall on Delvin Creek, located near the East Coast of Tasmania close to the small town of Mathinna.

The falls drop approximately 20–25 metres over their main visible tier, with additional hidden upper tiers adding to the overall spectacle. The site is reached via a roughly 1.

2-kilometre bush walk through lush, fern-lined forest that follows alongside Delvin Creek before arriving at the cascades. Visitors describe the falls as particularly impressive after rainfall, when the full set of four cascading tiers is on dramatic display.
