Strangways is a large impact structure, the eroded remnant of a former impact crater, located in the Northern Territory of Australia about 65 kilometres (40 mi) east-south-east of the town of Mataranka.

The circular topographic feature that marks the site was originally thought to be volcanic, with an impact origin first proposed in 1971 after the discovery of evidence diagnostic of impact including shatter cones and shocked quartz.

[3] The circular topographic feature is about 16 km (9.9 mi) in diameter and lies within Mesoproterozoic sedimentary rocks of the McArthur Basin.

Estimates of the original rim diameter vary between different researchers in the range 24–40 km (15–25 mi);[4] the Earth Impact Database[1] prefers a diameter of 25 km (16 mi).

[5] In 1996, the crater's site was listed on the now-defunct Register of the National Estate.
