The Oodnadatta Track is an unsealed 614 km (382 mi) outback road in the Australian state of South Australia, connecting Marla in the north-west via Oodnadatta to Marree in the south-east.

However, the D95 is not signposted, as the Department for Infrastructure and Transport has a policy of not marking unsealed roads.

[citation needed] The Oodnadatta Track heads southeast from Marla to Oodnadatta, and then roughly follows the former Central Australia Railway further southeast, until meeting the sealed Outback Highway at Marree.

Since the track is unsealed, the Government of South Australia recommends that users check whether it is open before departure.

Oodanadatta Track is entirely contained within the Outback Communities Authority local government area.
