Drosera hartmeyerorum is an Australian sundew in the section Arachnopus (Drosera indica complex). It is named in honour of Siegfried and Irmgard Hartmeyer, who contributed significantly to its discovery and description.

Drosera hartmeyerorum is a small to medium-sized sundew that grows about 5-30 cm tall. The leaves have a very short petiole without tentacles, but this is difficult to observe at a glance. The base of the leaves and bracts have distinctive yellow globular indumenta that resemble small blackberries in shape. The main stem is densely covered in small glands. The flower stalk has a sparse covering of glands, sometimes becoming glabrous towards the end. The flowers are metallic pink in colour with long, thin, curved stigmas. The foliage is commonly blood red. Plants growing in tough habitats often mature and bloom when small.

The species is endemic to the monsoonal north of Australia and is most commonly observed in the Kimberley Region, with sporadic records across the Northern Territory and one sighting in adjacent Queensland. I observed it growing in damp sand at the edge of ephemeral swamps and on moist clay in open fields.

Many sundews in the section Arachnopus (D. indica complex) can be distinguished by examining their indumenta. Drosera hartmeyerorum is distinguished from its relatives by its distinctive yellow blackberry-shaped indumenta.
