The dugite (/ˈdjuːɡaɪt/; Pseudonaja affinis) is a species of venomous, potentially lethal snake endemic to Western Australia, a member of the family Elapidae.

The word dugite is an anglicisation of names for the snake in some dialects of the Nyungar language, including dukayj and dukitj.

The dugite occupies a wide variety of habitats ranging from coastal dunes and heathlands to shrub lands and woodlands.

It also appears to thrive in heavily degraded habitats such as golf courses, industrial areas, and open agricultural farmlands.

[4] Dugites generally avoid biting humans, but risks of encounters increase when they are most active during the mating season through October and November.

[5] The last human death attributed to a dugite was in August 2015 in South Fremantle,[6] when a woman was bitten on her heel mid-afternoon while walking alone.

[citation needed] In January 2011, a seven-year-old Perth boy was bitten and temporarily paralyzed after a dugite entered his bedroom and wrapped itself around his arm while he slept.

In December 2020, a three-year-old girl was bitten by a snake, believed to be a dugite, while playing in a courtyard at her grandmother's unit complex in Mandurah.

In Chapter 16 of M. L Stedman's The Light Between Oceans, Septimus Pott's wife, Hannah Roennfeldt's mother, Ellen, a debutante from Perth, Western Australia died within an hour after being bitten above the ankle by a dugite.
