Orana is a vast region in north-central New South Wales, Australia.

[1] It has an area of 198,561 square kilometres (76,665 sq mi)[1] and is the largest region in New South Wales, comprising approximately 25% of that state.

Linguist David Nash suggests that Orana's true origin may be a Polynesian language, noting that Kia orāna is a common greeting on Rarotonga, the largest of the Cook Islands and Ia Orana in Tahitian means "hello".

[7] The output equals approximately A$658 million or 11.7% of the state's agricultural production.

[7] Wine made from the small number of vineyards in the Orana region may be labelled as Western Plains.
