Podocarpus laetus, Hall's tōtara, mountain tōtara or thin-barked tōtara, is a species of conifer in the family Podocarpaceae.[3] Previously known as Podocarpus hallii and Podocarpus cunninghamii,[4] in 2015 it was realised that the much earlier name P. laetus has priority.[5] Its common name results from the species being named after J. W. Hall, a New Zealand pharmacist.[3]

It is endemic to New Zealand. It can be found growing in both montane and subalpine forests but less common in lowland forests.[3]

P. laetus is distinguished from the more widely known lowland tōtara by its thinner bark,[6] longer juvenile leaves and distribution at higher altitudes.[7][8]

P. laetus plays host to the endemic insects Ambeodontus tristis and Oemona hirta.[9]
