Dynevor is a locality in the Shire of Bulloo, Queensland, Australia.
Dynevor is in the Channel Country. It is arid land, mostly flat and approximately 150 metres above sea level. Although there is a network of mostly unnamed creeks through the locality, these are usually dry creek beds. An area of higher land (about 200 metres above sea level runs north to south through the locality, resulting in the creeks in the west of the locality forming part of the Bulloo River drainage basin and in the east of the locality forming part of the Paroo River drainage basin.
The land is predominantly leased for pastoral purposes, the northern part of the locality being the Dynevor Downs pastoral lease (and presumably the source of the locality name). The north-west part of the locality contains the entire Lake Bindegolly National Park while a portion of the Currawinya National Park can be found in the north-east although the bulk of that national park is in adjacent Hungerford.
The Cunnamulla Road (also known as the Bulloo Developmental Road and the Adventure Way) from Thargomindah to Cunnamulla passes from west to east through the northern part of the locality. The Hungerford Road from Thargomindah to Hungerford passes from north to south through the western part of the locality.
There is no town in the locality but the town of Thargomindah is only 1km from the locality's north-west boundary and the town of Yowah is 4km from the locality's north-east boundary. The Dynevor Downs Homestead is located on the Cunnamulla Road (28°05′46″S 144°21′53″E / 28.0960°S 144.3648°E) and has the Dynevor Downs Airport (ICAO: YDNV) with three runways (north-south, east-west, and NE-SW), the longest being 1050 metres, the others being about 800 metres.
