Teranodes montanus is a species of funnel-web spider in the Hexathelidae family. It is endemic to Australia. It was described in 1927 by Australian arachnologist Vernon Victor Hickman.
The species occurs in Tasmania and Victoria, in closed forest habitats. The type locality is the Higgs Track, Great Western Tiers, near Chudleigh, Tasmania.
The spiders are fossorial, terrestrial predators that build silk-lined burrows beneath rocks and rotten logs.
